Hello World using Function in C++

---

This is a C++ program that prints "Hello World!!!" to the console using a function called call(). The program begins with the inclusion of the input/output stream library iostream. This allows the program to use the cout object, which is used to print text to the console.

The call() function is defined to print the text "Hello World!!!" to the console using the cout object. The function does not take any parameters and does not return any value. In the main() function, the call() function is called, which results in "Hello World!!!" being printed to the console. Finally, the program returns 0, indicating that it executed successfully.

Source Code

#include <iostream>
using namespace std;
void call()
{
    cout<<"\nHello World!!!";
}
int main()
{
    call();
    return 0;
}
