Write a C++ program which define function with argument and a return value.

Write a C++ program which define function with argument and a return value.

Here we are considering display() function as user defined function which further takes two number as argument and an integer value as return type.

Program Code:

#include <iostream>

using namespace std;

// user defined function with return value (int) and have two argument of int type

int display(int x, int y) 

{ 

int c; 

c = x + y;

return c;

} 

// main() function with user defined function call

int main() 

{ 

int a, b, x; 

cout<<"Enter number a : ";

cin>>a;

cout<<endl;

cout<<"Enter number b : ";

cin>>b;

cout<<endl;

// user defined function call in the main() function with two argument in it

x = display(a,b); 

cout<<"Addition of a and b : "<<x;

return 0;

}

The program output is tested on www.jdoodle.com

Output:

Enter number a : 2

Enter number b : 3

Addition of a and b : 5
