POWER CALCULATION

• Problem Description

  
  Write a Program to calculate power using recursion.

• CODING ARENA::

• #include <stdio.h>

  int power(int n1,int n2);

  int main()

  {

    int a,b,c;

    scanf("%d%d",&a,&b);

    c=power(a,b);

    printf("%d^%d = %d",a,b,c);

    return 0;

  }

  int power(int a,int b)

  {

    if(b!=0)

      return(a*power(a,b-1));

    else

      return 1;

  }

• Test Case 1

  
  Input (stdin)

  2 3
  
  

  Expected Output

  2^3 = 8

• Test Case 2

  
  Input (stdin)

  2 2
  
  

  Expected Output

  2^2 = 4
