C Program to find Power of a Number using Recursion

The following C program, using recursion, finds the power of a number. The power of a number is the number multiplied to itself for the number of times it has been raised to Eg: 7^3 is 343

Here is the source code of the C program to find an element in a linked list. The C Program is successfully compiled and run on a Linux system. The program output is also shown below.

Enter a number: 456
Enter it's power: 3
456^3 is 94818816
