C++ program to calculate m to the power n

C++ Program to calculate m to the power n(m raise to n).

Example :

2² = 4 which is same as 2 x 2 = 4
4⁴ = 256 which is same as 4 x 4 x 4 x 4 = 256

Code :

#include <iostream.h>
#include <conio.h>
int power(int,int);
void main()
{
    int no,pow,val;
    clrscr();
    cout<<"Enter number : ";
    cin>>no;
    cout<<"Enter the power : ";
    cin>>pow;
    val=power(no,pow);//called function power which returns integer
    cout<<"The answer is : "<<val;
    getch();
}
int power(int no, int pow)
{
    int val;
    val=no;
    while(pow>=1)
    {
        if(pow==1)
            return no;
        if(pow>1)
            val=val*no;
        pow--;
    }
}

Output :

Enter number : 2
Enter the power : 8
The answer is : 256

Note : Since the type of number is integer the range of number which it can calculate is restricted.
