How to calulate power of an integer number using recursion in c

Write a program in c using recursion to calculate the power of an inter number. The number and power will be entered by user.

 

In this program we shall learn through a program that how to calculate power of an integer number using recursion in c programming language. In this program ask for a number and power to be calculated to the user, and display the corresponding value of the power of number.

Example:

Enter number = 5

Enter power  = 3

Calculated value = 125

Now see the program:

#include<stdio.h>
#include<conio.h>
int Power(int,int);
int main()
{
    int number,power,result;
    printf("Enter number\t");
    scanf("%d",&number);
    printf("Enter the power to be calculated\t");
    scanf("%d",&power);
    result = Power(number,power);
    printf("The result of %d to the power %d is = %d\n",number,power,result);
}
int Power(int a,int b)
{
    static int r = 1;
    if(b == 0)
    {
        return(1);
    }
    else
    {
        r = r*a;
        Power(a,b-1);
    }
    return(r);
}

Output:

Enter number = 6
Enter the power to be calculated = 2
The result of  6 to the power 2 is  = 36
