Write a program that uses a function power() to raise a number m to power n. The function takes int values for m and n and returns the result correctly. Use a default value of 2 for n to make the function calculate square of m when the value for n is missing while calling


#include<iostream.h>
#include<conio.h>
#include<math.h>


double power(int m, int n = 2)
{
double res = pow(m,n);
return res;
}


void main()
{
int x;

cout<< "\n Enter a number to calculate its square :";
double d = power(x);
cout<< "\n The square of " << x <<"is " << d;


cout<< "\n Enter a number to calculate its cube :";

 d = power(x,3);
cout<< "\n The cube of " << x <<"is " << d;



int y;
cout<< "\n Enter a number  and its power to calculate the result :";
cin>>x>>y;

d = power(x,y);
cout<< "\n The " << x << " to the power " << y <<" is " << d;
getch();
}
