Function Overloading:

Write a program to explain function overloading with the different number of arguments Function Overloading:

C++ enables two or more functions with the same name but with different types of arguments or with the different number of arguments. This capability to overload a function is called function overloading.

Program Code:

#include<iostream>

using namespace std;

int sum(int, int);

int sum(int, int, int)

void main()

{

int x=5;

int y=10;

int z=20;

int a=0,b=0;

a=sum(x,y);

b=sum(x,y,z);

cout<<"Sum of two integers = "<<a<<endl;

cout<<"Sum of three integers = "<<b<<endl;

}

int sum(int x,int y)

{

return(x+y);

}

int sum(int x,int y,int z)

{

return(x+y+z);

}

Output:

Sum of two integers = 15

Sum of three integers = 35
