define the role of cache memory in computers.

Answer:

Java provide all the ADTs you need,therefore you do not need to create any newones.

This statement is not true.

Explanation:

ADTs are those data types which we use but we didn't know their inner working that is how it is working what is happening inside.It is commonly used for Data Structures for example:- In stack we use push and pop operations to insert and to delete element from a stack respectively but we didn't know how it is happening inside.How the stack is implemented and etc.Java provides most of the ADT's but not all.

The statement that is wrong as regards abstract data types in this question is C: Java provides all the ADTs you need, therefore you do not need to create any new ones.

Examples of ADT are;

Therefore, option C is correct.

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.

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.

Answer: False

Explanation:

This code code not deletes element from deq. This insert element at the beginning of deq. if it was deq.pop_front(elem) then it would have deleted the first element.

Therefore, it is false.

Answer:

#include<iostream>

using namespace std;

//main function

int main(){

   //initialize the variables

   int side;

   //print the message

   cout<<"Please enter the side of square: ";

   cin>>side;  //read the vale and store in the variable.

   // for loop

   for(int i=1;i<=side;i++){  //lop for rows

       for(int j=1;j<=side;j++){   //loop for column

           cout<<"$";  //print the '*'

       }

       cout<<endl;

   }

}

Explanation:

Create the main function and declare the variable side.

print the message on the screen for the user and then store value enter by the user on the variable side.

take the nested for loop for print the pattern.

nested for loop means, loop inside another loop it is used for print the pattern having rows and columns.

the first loop updates the row number and the second the loop print the character '$' in the column-wise.

in the code,

if i = 1, for loop check the condition 1 <= 5 if the value of side is assume 5.

condition is true and the program moves to the second for loop and starts to print the character '$' five times after that, print the new line.

then, the above process repeat for different rows and finally, we get the pattern in square shape.

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.

Answer:

Answer is (a) reserve

Explanation:

Usually when we create an array variable, in some language the memory is allocated automatically. But in some the memory is not allocated automatically. So we need to reserve the memory space for the array.

For example in C++ dynamic memory allocation we need to allocate memory using new keyword.

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.

Answer: The QA/Testing process consist of the following:

1. Requirement specification

2. Reviewing the code.

3. Unit testing

4. Integration test

5. Performance testing

Explanation:

We start of by the requirement specification try to gather all the information accurately. Then begins the coding process where there is review of the code so that they perform their desired purpose. After modules are completed we perform unit testing of the different modules individually and also do the integration testing once all the modules are completed. At the end we perform the performance testing to take a note on their desired output and other quality parameters.

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.

Answer:

Explanation:

Answer:

Serial communication are connected using 2 types of connector

Explanation:

The two types of connector for serial communication are:

1. Nine pin connector.

2. Twenty five pin connector.

for 9 pin connector we have:

pin 1 = data carrier detect

pin 2= received data

pin 3= transmitted data

pin 4= data terminal ready

pin 5= signal ground

pin 6= data set ready

pin 7= request to send

pin 8= clear to send

pin 9= ring indicator

Here, the minimum number of pins can be pin 2,3 and 5 which are receive, transmit and ground signal to establish a communication without handshaking.

The minimum number of pins actually depend on the type of software we use.

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'.

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.

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.

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.

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.

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.
