What is the Moore's law

We power on the computer before we begin because a computer has a special programme in it called operating system which needs to be started for us to use the computer

Answer: so i can turn on and you could do what ever u want

Explanation:

Answer:

#include<iostream>

using namespace std;

//create the function which add two number

void addTwoNumber(int num_1,int num_2)

{

   int result = num_1 + num_2;  //adding

   cout<<"The output is:"<<result<<endl;  //display on the screen

}

//main function

int main(){

   //calling the function

   addTwoNumber(3,6);

   return 0;

}

Explanation:

First, include the library iostream for using the input/output instructions.

then, create the function which adds two numbers. Its return type is void, it means the function return nothing and the function takes two integer parameters.

then, use the addition operation '+' in the programming to add the numbers and store the result in the variable and display the result.

create the main function for testing the function.

call the function with two arguments 3 and 6.

then, the program copies the argument value into the define function parameters and then the program start executing the function.

Answer:

#include<iostream>

using namespace std;

int digits(int number){

   int sum=0;

   while(number != 0){

       int rem = number % 10;

       sum = sum + rem;

       number = number/10;

   }

   return sum;

}

int main(){

   int number;

   cout<<"Enter the integer: ";

   cin>>number;

   int result = digits(number);

   cout<<"The sum of digits is: "<<result<<endl;

}

Explanation:

Include the library iostream for use of input/output.

Then, create the function digits with return type int.

Take a while loop and put a condition number not equal to zero.

the while loop executes the until the condition is not false.

In the while loop, take the remainder of the number and store in the rem variable.

after that, the store in the sum then reduces the number by dividing 10.

for example:

the number is 123.

rem = 123%10 it gives the value 3.

sum = 0+3=3

number = 123/10 it equal to 12

then,

rem = 12%10 it gives the value 2.

sum = 3+2=5

number = 12/10 is equal to 1

the same process executes until the number becomes zero and then the while loop terminates and the sum value returns to the main function.

create the main function and take the value from the user and call the function with the argument number.

and finally, print the result.

Answer:

an immediate.

Explanation:

It is because of the instruction encoding and decoding.Intel which make these instructions decided not include instructions which provide no real advantage. MOV segment register is one of them because segment register need not to be changed very often.This saves the space in instruction encoding.

Answer: In the MOV instruction both operands i.e., source and the destination cannot be immediate operands.

Explanation:

The destination operand must be in data alterable mode and it cannot be an an immediate operand, or a segment register. Basically, the mov operation are used to copy the values stored in one registers to another registers. It can be used to load a small integer in the register.

Answer:

The correct answer is b. Asymmetric Distribution.

Explanation:

Asymmetric Distribution has to do with those larger workloads which are issued to IT resources with higher processing capacities. The Pay-Per-Use Monitor is where the billing system relies on. The Workload Prioritization is where workloads are prioritized according to their level. And the SLA monitor is a contract between a service provider and the customer. So, the most correct answer is b.Asymmetric Distribution.

Answer:

Digital electronics involves 2 states which are abstracted as 0/1 or true/false.

Explanation:

Digital electronics involves 2 states. For TTL logic this corresponds to 0 Volt (0) or 5 Volt (1). Analyzing further, a  digital waveform has a square shape  (not necessarily a perfect square) with 2 levels denoting the two states, namely, true(1) or false(0). So a 0 or 1 is not actually absolute but 0 corresponds to voltage level below a threshold voltage whereas 1 corresponds to voltage level above a threshold voltage.

The main functions of a traffic light controller are listed below:

Answer:

Clock rate also known as clock speed is the rate at which microprocessor executes instructions.That means clock rate is directly proportional to the execution speed of an instruction.Microprocessor is the core of a computer a system it contains all the functions of a central processing unit.So if the clock rate is more  execution speed of an instruction is more if clock rate is less execution speed of an instruction is less.

Answer:

1. ‘cout’ was not declared in this scope.

2. ‘cin’ was not declared in this scope.

3. lvalue required as left operand of assignment.

Explanation:

The code gives the error cout and cin was not declare. This error means, we not include the library where they define.

cout and cin is the input/output instruction and they include in the library iostream file.

the last error is lvalue required as left operand of assignment.

lvalue means the assignable value, we actually do the wrong assignment.

number1 + number2 = sum;

here, sum is is the assignment variable. so, it must be in the right side of the '=' operator.

sum = number1 + number2 ;

Now, the above is correct. the value number1 plus number2 is assign to sum.

Answer:

It is an error in the program that warns the users that something is wrong in the data they have entered

Explanation:

Null pointer exception, ArrayIndexOutOfBounds and arithmetic exception are some of the exception which can be thrown in a code segment. example if we use divide by zero then the exception to be used is arithmetic exception. Similarly we can also define our own conditions for throwing an exception using the keyword throw. Example throw exception class("error message"),

As, windows XP has suffered from security problems or issues with the performance. Vista has received issue with product activation and performance. Another common problem of Vista is that integration of new form of DRM in the operating system and security technology.

Answer:The answer is (c).first.

Explanation:

In doubly linked list each node possesses the address of next node(except last node) because there is no node present after the last node .

and the address of previous node(except first node) because there is no node present before the first node.

So the conclusion is that the first node does not contain the address of previous node and the last node does not contain the address of the next node.

Answer:

The final value of i will be 5 at the end of the program.

i=0, i≤4, prints 0.

i=1, i≤4, prints 1.

i=2, i≤4, prints 2.

i=3, i≤4, prints 3.

i=4, i ≤ 4, prints 4.

i=5, i is not ≤ 4, stops here.

Q-5:

pow(2,3) = 8 and pow(3,2)=9, so they are not same.

Q-6:

The functions pow(), sqrt(), and fabs() are found in which cmath

Explanation:

Final answer:

The final value of i is 5. pow(2,3) is not the same as pow(3,2). The functions pow(), sqrt(), and fabs() are located in the cmath include file.

Explanation:

Final Value of Variable i

The final value of i at the end of the loop in the C++ code is 5. This occurs because the loop continues to increment i until the condition i <= 4 is no longer true. After the last execution with i equal to 4, the loop increments i to 5 and then checks the condition, which fails, thus exiting the loop and leaving i with a value of 5.

Power Function Comparison

pow(2,3) is not the same as pow(3,2). The pow function returns the value of one number raised to the power of another. Thus, pow(2,3) calculates 2 to the power of 3 (2*2*2), which equals 8, while pow(3,2) calculates 3 to the power of 2 (3*3), which equals 9.

Function Include Files

The functions pow(), sqrt(), and fabs() are all found in the cmath include file of C++.

Final answer:

ETL functions are challenging in a data warehouse environment due to the high volumes of data, the variety and inconsistency of data formats and structures, and the imperative need to maintain data quality.

Explanation:

ETL, which stands for Extract, Transform, Load, is a critical process in a data warehouse environment. It involves the integration of data from multiple sources, transformation of that data into a format suitable for analysis, and then loading it into the data warehouse.

There are three main reasons why ETL functions can be particularly challenging in this setting:

Data Volume: The sheer amount of data that needs to be processed can be overwhelming. Handling large volumes of data requires robust systems and can be time-consuming, thus posing a significant challenge.

Data Variety: Different data sources can mean inconsistent formats, structures, and quality. Achieving consistency and accuracy in data transformation is a difficult task that demands meticulous attention to detail and sophisticated processes.

Data Quality: Ensuring the correctness, completeness, and reliability of data is paramount. This can be a daunting task due to potential errors in the data and the complexity of data validation rules.

The challenges of ETL highlight the importance of having a well-designed data warehouse architecture and a comprehensive approach to data management.

Answer: True

Explanation:

Embedded system processor are more powerful than general purpose processor because the embedded  processors are designed to work in a particular machine for which they get the right amount of RAM and hardware however general purpose processors are to work in every machine which makes them little slow in some machine as they do not get the proper hardware and RAM and have to cope with much more demanding situations.

Answer: Lisp which is the short for list processing is a special purpose programming language and it was developed for processing strings which is being exploited in the field of artificial intelligence.

Explanation:

Lisp is used for artificial intelligence as it can compute symbolic expressions, so a common lisp which it later came to be known as is used for development of application with artificial intelligence and is being widely used today. Lisp was actually developed in the early 1980s.

This statement simply checks if minimum is True. If it is, then it assigns 10 to the hours variable.

Answer:

java programming language is a programming language which is based on the concepts of object oriented programming.

Explanation:

Java program uses the concept of classes and enable to use the classes by making objects of them. Java program is similar in concepts to that of C++. java program can run on a single system or can also be shared across a network. It is considered to be safe and it is interpreted by JVM (Java virtual machine). Some of its characteristics are it exhibits polymorphism, inheritance and overloading and overriding functions.

Java is used for developing many web based application, software's and games. These program are easy to write, debug and compile with perfect GUIs for which it is considered to be user friendly.

cout << "Enter the shape (1 for rectangle,2 for triangle, 3 for circle): ";

//Asking user for the shape

cin >> s;

switch(s)  //checking which shape it chooses

{

case 1:

rectangle();  //If user type 1 ,then calling rectangle function

break;

case 2:

triangle();   //If user type 2 ,then calling triangle function

break;

case 3:

circle();  //If user type 3,then calling circle function

break;

default:

cout <<"Enter valid choice for shape";  //If user type other than 1,2,3

}

return 0;  

}

Output

Enter the shape (1 for rectangle,2 for triangle, 3 for circle): 1

Enter height:2

Enter width: 3

The perimeter of the rectangle is 10 and the area is 6

Answer: The shell sort is based on insertion sort. Here the list of elements are divided into smaller sub list which are sorted based on insertion sort.

Its best case time complexity is O(n* logn) and worst case is O(n* log^2 n)

Explanation:

Shell sort is an inplace sorting here we begin by dividing the list into sublist and sorting the list with insertion sort. We create interval for dividing the list into sub list until we reach the smallest interval of 1.

The best case is O(n* logn).

Answer:

8 times

Explanation:

The while is execute again and again until the condition is TRUE.

In the question:

the value of i=2, when program enter the loop it check the condition when

2 <= 16, condition TRUE. it update the value i = 4.

Again the loop check condition, 4 <= 16, condition TRUE, i become 6 and so on...

4,6,8,10,12,14,16

when i = 16 loop condition is also TRUE. 16 <= 16. So, it again run the loop and i become 18.

then, the loop condition false and it exit the loop.

so, i run until 18

4,6,8,10,12,14,16,18

Therefore, the answer is 8 times.

cout<<"Input string: "<<endl;

/*getline()method is used to store the characters from Input stream to strin string */

getline(cin,strin);

//size()method returns the length of the string.

int length=strin.size();

//tolower() method changes the case of a single character at a time.

// loop is used to convert the entire Input string to lowercase.

while (strin[i])

{

  char c=strin[i];

  low_string[i]=tolower(c);

   i++;

}

//Checking the length of characters is less than 80

if(length<80)

 {

    cout<<"Output string: "<<endl;

   //Printing the Input string in reverse order, character by character.

    for(int i=length-1;i>=0;i--)

   {

    cout<<low_string[i];

   }

cout<<endl;

}

else

    {

       cout<<"string Length Exceeds 80(Max character Limit)"<<endl;

    }

return 0;

}

Output-
