#include<iostream>

using namespace std;

int main(){

   if(num % 2 == 0){

Answer 2

$\star\:\:\:\sf\large\underline\blue{Question:-}$

• Write a sample program of C or C++.

$\star\:\:\:\sf\large\underline\blue{Example\:Program:-}$

• This is an example program to print hello world.

1. #include <iostream.h>
2. int main()
3. {
4. std:: cout<< "Hello World!!!!";
5. return 0;
6. }

$\star\:\:\:\sf\large\underline\blue{Output:-}$

Hello World!!!!!

How it works?

Line number 1:

Here #include is a preprocessor directive used to include files in a program.

Line number 2:

Given line indicates the main function. The curly braces indicate the starting and ending of the function. From here, execution starts.

Line number 4:

This line is used to print Hello World!!

std::cout<< prints the content inside the question mark. Semicolon is used to mark the end of the statement.

Line number 5:

return 0 is the exit status of the program. Here, the program terminates.
