An interface does not have ____.
A) return types
B) instance fields
C) abstract methods
D) public methods
Answer:
B - instance fields
Explanation:
Fields/variables declared within interfaces are by default final, public or static and hence will not be considered as an instance variable/field but a class variable. Although interfaces can be used to define instance methods, they will never have instance variables.
The searching algorithm of ordered array is faster than regular array, but the insertion time is slower than regular array. True or False?
Answer:
True
Explanation:
In an ordered array or sorted array, we can implement binary search which uses branch prediction to search for values within the array. In binary search the array is divided into two halves. With the help of branch prediction we can easily find out in which part of the array the value may reside. Thus it drastically reduces the searching time. Whereas in a linear array, the array elements needs to be searched sequentially one after the other to match with the search element. Thus searching algorithm of ordered array is faster than regular array.
In a regular array, the insertion operation is faster than an ordered array because there we don’t have to decide the position at which the element needs to be inserted. In a regular array we can simply insert the new element to be added at the end of the array.
Thus the insertion time of an ordered array is slower than regular array.
if x is -1, what is the value of (!(x == 0))?
false
true
unable to determine
invalid syntax
Answer:
true
Explanation:
The operator '!' used in the question is called NOT operator which invert the value of Boolean.
if the value is TRUE, output will be FALSE.
if the value is FALSE, output will be TRUE.
The operator '==' is used for comparison, if both values are equal then it gives TRUE otherwise FALSE.
The value of x is -1.
so, (-1 == 0) which is FALSE. -1 and zero are not equal.
then, !(FALSE) which gives TRUE output.
Therefore, the answer is true.

Explain the following terms in a sentence or two in C++context.a)Orthogonalityb) Expresibilityc) Language domain andparadigmd)Portability
Answer:
a)Orthogonality
IBM C++ implements compatibility characteristics at the C 99 language stage and with GNU C language extensions to maintain compatibility as a super-set of C. IBM C++ also promotes a subset of C++ GNU extensions. Like the IBM C language extensions, the orthogonal and non-orthogonal language functions of the C++ extensions.
b) Expresibility
Expresibility relates to what can be said in the language of regular expression, most lex generators enable sets of letters, Kleene star(Vˣ) and plus, and alternation. Consider what happens if you have C++ with embedded assembly code: the C++ code is likely to belexer under one set of rules, and the management of lexical mode indicates how control can be transferred from one mode to another.
c) Language domain and paradigm
C++ is a programming language that promotes multiple paradigms, including classes, overloaded features, templates, modules, and more.
Using C++ wealthy collection of over-loadable operators as a domain-specific language, a category representing a matrix could overload multiplication(*) and other arithmetic operators, enabling implementation codes to be handled similarly to the numerical sort.
d) Portability
C++ includes the entire variety from low-level to high-level programming, making it ideal for composing portable software, but in embedded systems engineering code portability is often overlooked. With software becoming increasingly complicated, and hardware becoming increasingly interchangeable, this supervision becomes a issue when software has to be transported to a new platform.
Because an AVL tree is a binary search tree, the search algorithm for an AVL tree is the same as the search algorithm for a binary search tree.
True
False
Answer:
True, Yes the search algorithm for AVL tree and the binary search tree are same.
Because in both trees, of a certain a node, the smaller elements reside in the left sub-tree and the larger elements reside in the right sub-tree.
Explanation:
So while searching an element in the AVL tree we start the search from the root node.
We compare the element to be searched with the root node.
if (element < root node), then move in left and compare with it's left child.
else move in right and compare with it's right child.
Similarly in next phase move accordingly as in the binary search tree.
What is the output of the following code segment? int n = 0; for (int k = 0; k< 2; k++) {n=n +2;} cout << n; oo 0 1 O O O
Answer:
4
Explanation:
The loop is used to execute the part of code or statement again and again until a condition is not true.
syntax of for loop:
for(initialize; condition; increment/decrement){
statement;
}
in the question, the value of n is zero.
then, for loop check the condition k<2, initially the value of k is zero. so, the condition is true and execute the code n = 0 +2=2
Then, k is increment by 1. so, the value of k is 1.
then, again loop run and check the condition 1<2, it true. then n = 2+2=4.
then, k is increment by 1. so, the value of k is 2.
Then, again check the condition 2<2, condition false and program terminate the loop and finally print the value 4.
What is difference between rand() and srand() ?
Answer:
rand() function generate the random number within the range.
srand() function decide the starting point for random function or set the seed for rand() function.
Explanation:
rand() function which is used to generate the random number within the range.
srand() function is used to decide the starting point for random function.
In sort meaning, it set the seed for rand() function.
if srand() function not used, the random function generate the same output again and again because the starting point is fixed for generating the random number.
if srand() function used it change the starting point every time and random function generate the output different in every time.
A final class can't be extended.
*True
*False
Answer:
The answer is True.
Explanation:
The final class cannot be extended because in java final keyword means "no modification". If it is applied to a variable or anything else then that value becomes a constant after that it cannot be modified.So in cases of class if final keyword is used it means that class cannot be extended.
The true or false questions.
The command: egrep -l 'cis' * will show the name of all files in the current directory where the name contains the word 'cis'
Answer:
True
Explanation:
egrep command is basically used for text filtering and is an modified version of grep. using -l with egrep implies it returns the names of the matching files but does not return the line number. Following this we have the keyword here in the question it is 'cis' and * stands for the entire directory search. Therefore, the command egrep -l 'cis' * will show the names of all files in the directory with the word 'cis'.
What is meant by Program Memory is paged?
Answer:
Program memory is paged, this statement is defined as in a computer system paged memory is the process of allocation of memory and storing a portion of a process of execution. Page is a unit of logical memory in a program. It follows the process of paging, as it is a method of writing an information and reading the output from the storage drive. The main advantage of this process is that it become easy to swap because everything is the same size.
If you want a user to enter exactly 20 values, which loop would be the best to use?
1. do-while
2. while
3. for
4. infinite
5. None of these
Answer: For loop
Explanation:
Using the for loop we can get the exact number of values/outcomes we require.
For example: printf(enter 20 numbers");
for(int i=0; i<20;i++)
{
scanf("%d", &number);
}
So, this is an implementation of for loop in C. Using it we can enter exact 20 numbers not less or more than that.
Therefore, for loop is the answer.
The for loop is the best choice when you want to run a loop a known amount of times. In this specific example, you can use the for loop to gather 20 pieces of user input.
Explanation:If you want a user to enter exactly 20 values, the best loop to use would be the for loop. The for loop is specifically designed for situations where we know in advance how many times the loop needs to execute. In this case, we know the loop needs to execute exactly 20 times to accept 20 input values from the user, so using a for loop would be the most appropriate choice.
Here's an example of how you can structure a for loop in this situation:
for(int i = 0; i < 20; i++) {
// User input code here }
This loop will run 20 times, allowing you to gather 20 pieces of user input.

What is the importance of Mathematical Modeling in the field of bioinformatics.
Answer: mathematical modelling helps to look into the uncertainties in the calculations based on the observational data.
Explanation:
In bioinformatics for example in gene data expression there can millions of data obtained through various observatory experiments. however most of the data is inadequate to arrive at at a conclusion. So in order to solve this issue we have to apply mathematical modelling to consider those data which would help us to understand the models behavior and access its performance.
Final answer:
Mathematical Modeling is critical in bioinformatics, enabling the analysis of large datasets and the development of new frameworks necessary for understanding complex biological systems. It aids in sequence comparison, hypothesis testing, and simulation of biological systems, often in conjunction with experimental validation.
Explanation:
The importance of Mathematical Modeling in the field of bioinformatics cannot be overstated. Bioinformatics, a field that marries biology with computer science, relies heavily on Mathematical Modeling to sift through and make sense of the vast datasets generated by modern biological research, such as genome sequencing and gene expression profiling. Computational power and Mathematical Modeling enable biologists to perform sequence comparisons, test hypotheses, and create in silico research that might predict biological phenomena. It is especially necessary for managing the complexities brought about by Next-Generation Sequencing technologies, requiring the development of new statistical and theoretical frameworks.
Mathematical models in bioinformatics are crucial for describing scientific phenomena and evaluating costs, requiring the application of various mathematical skills and concepts like algebra, calculus, and statistics. They support the engineering design process within bioinformatics by enabling the construction of comprehensive simulation models. These models are instrumental in understanding the structure and behavior of biological systems, sometimes even without direct experiments. However, it is critical to validate these models with observations to ensure their accuracy and efficacy.
In summary, Mathematical Modeling serves as a fundamental tool for bioinformatics specialists, assisting them in processing and interpreting large datasets to advance our understanding of biological systems and processes. It is a bridge between theoretical biology and practical computer-based analysis that is essential for data-driven discoveries in bioinformatics.

____ is the encapsulation of method details within a class.
a.
Implementation hiding
b.
A calling method
c.
Instantiation
d.
An interface
Implementation hiding is the encapsulation of method details within a class. Implementation can be interpreted as those specifications which can be altered without altering the correctness of an application. Wrapping data/methods within classes (descriptions of the way all objects of this type will look/act) in combination with implementation hiding is called encapsulation. Information users need to know about behaviors should be available without dependence on implementation specifications.
Output a brief description of the game of hangman and how to play.
Answer:
Hangman is game which can be played with a pencil or pen and a paper. It is a multiplayer game which requires minimum two players. It is a guessing game, in which a player thinks of a word or a phrase and other player or players tries to guess it correctly, letter by letter or whole word or phrase at once, in a certain number of guesses.
In this game, the word to be guessed is represented by dashes. If the guessed word or letter is correct, the player fills the blank spaces. But if the guessed word or letter is wrong, the player draws an element of a hanged man stick figure one by one as a tally mark.
This game ends if the player who is guessing guesses the word or the phrase correctly and the guesser wins; or if the player guesses enough wrong letters of phrases that the other player finishes the drawing of the hangman and the guesser loses.

prove that the dual of the exclusive-OR gate is also itscomplement
Answer:
Explanation:
The dual of a function means replace AND with OR and replace OR with AND.
XOR gate of A , B is
[tex]A \, XOR\, B = AB' + A'B[/tex]
So, Dual of A XOR B is ( replace AND with OR and OR with AND)
[tex]= (A+B')(A'+B)[/tex]
Complement of A XOR B is [tex](A XOR B) ' = (AB' + A'B) ' = ((A)' + (B')') ((A')' + (B)') = (A'+B)(A+B')[/tex] (In finding compliment AND becomes OR and OR becomes AND ).
By inter changing the above product of terms
Complement of [tex]A XOR B = (A + B') (A' + B)[/tex]
So, Dual of A XOR B = Complement of A XOR B.

A painting company has determined that for every 115 square feet or wall space, one gallon of paint and eight hours of labor will be required. The company charges $.18.00 per hour for labor . Write a program that allows the user to enter the number of rooms to be painted and the price of the paint per gallon. It should also ask for the square feet of wall space in each room. The program should have methods that return the following:
* The number of gallons of paint required
* The hours of labor required
*The cost of the paint
*The labor charges
*The Total cost of the paint job
The program to calculate the total paint cost and other values is given below.
#include <iostream>
using namespace std;
int main() {
int rooms, laborChrg = 18;
float paintChrg;
float feetPerRoom[rooms];
float paintReq, laborHrs, paintCost, laborCost, totalCost, totalsqft=0;
cout<<"Enter the number of rooms to be painted "<<endl;
cin>>rooms;
for(int i=0; i <= rooms; i++)
{
cout<<"Enter the square feet in room "<<endl;
cin>>feetPerRoom[i];
// shortcut operator which is equivalent to totalsqft = totalsqft + feetPerRoom[i];
totalsqft += feetPerRoom[i];
}
cout<<"Enter the cost of the paint per gallon "<<endl;
cin>>paintChrg;
laborHrs = (totalsqft/115)*8;
laborCost = laborHrs * laborChrg;
paintReq = totalsqft/115;
paintCost = paintReq * paintChrg;
totalCost = laborCost + paintCost;
cout<<"The number of gallons of paint required "<<paintReq<<endl;
cout<<"The hours of labor required "<<laborHrs<<endl;
cout<<"The cost of the paint is "<<paintCost<<endl;
cout<<"The labor charges are "<<laborHrs<<endl;
cout<<"The Total cost of the paint job is "<<totalCost<<endl;
return 0;
}
Explanation:
The header files for input and output are imported.
#include <iostream>
using namespace std;
All the variables are taken as float except labour charge per hour and number of rooms.
The user is asked to input the number of rooms to be painted. An array holds the square feet in each room to be painted.
cout<<"Enter the number of rooms to be painted "<<endl;
cin>>rooms;
for(int i=0; i <= rooms; i++)
{
cout<<"Enter the square feet in room "<<endl;
cin>>feetPerRoom[i];
totalsqft += feetPerRoom[i];
}
The above code asks for square feet in each room and calculates the total square feet to be painted simultaneously.
All the data to be displayed is calculated based on the values of labor charge per hour and gallons of paint needed, given in the question.
laborHrs = (totalsqft/115)*8;
laborCost = laborHrs * laborChrg;
paintReq = totalsqft/115;
paintCost = paintReq * paintChrg;
totalCost = laborCost + paintCost;
All the calculated values are displayed in the mentioned order.
