This program takes two integers from user ( base number and a exponent) and calculates the power. Instead of using loops to calculate power, this program uses recursion to calculate the power of a number.
Source code to calculate power using recursion
/* Source Code to calculate power using recursive function */
int power(int n1,int n2);
int base, exp;
printf("Enter base number: ");
printf("Enter power number(positive integer): ");
printf("%d^%d = %d", base, exp, power(base, exp));
int power(int base,int exp)
if ( exp!=1 )
Enter base number: 3
Enter power number(positive integer): 3
3^3 = 27
This program can only calculate the power if base power and exponent are integers only. If you need to the calculate power of a floating point number then, you can use pow() library function.
