Write a C++ program which define function with no argument and no return value.

Write a C++ program which define function with no argument and no return value.

In this program we are taking display() as user defined function with no return type and have no argument passed in it.

Program Code:

#include <iostream>

using namespace std;

// user defined function with no argument and have no return type

void display() 

{ 

int x; 

cout<<"Enter a Number to display : "; 

cin>>x; 

cout<<endl;

cout<<"You Entered value of a : ";

cout<<x;

} 

// main() function with user defined function call

int main() 

{ 

int a; 

// user defined function call in the main() function

display(); 

return 0;

}

The program output is tested on www.jdoodle.com

Output:

Enter a Number to display : 2

You Entered value of a : 2

Thanks
