CPP program to illustrate function overloading

In this article we will learn to implement a CPP program to illustrate function overloading. A C++ program is provided below to demonstrate function overloading using 2 overloading functions for power.

Program is as follows:

#include <iostream>
#include <cmath>
using namespace std;
int power(int x)
{
	return pow(x, 2);
}
int power(int x, int n)
{
	return pow(x, n);
}
int main()
{
	int x;
	cout<<"Enter a number: ";
	cin>>x;
	cout<<"x^2="<<power(x)<<endl;
	int n;
	cout<<"Enter power value: ";
	cin>>n;
	cout<<"x^n="<<power(x, n)<<endl;
	return 0;
}

Input and output for the above program are as follows:

Enter a number: 4
x^2=16
Enter power value: 4
x^n=256
