Program To Calculate Power Using Function

#include <stdio.h>
double power(int a, int b);
int main()
{
    int a, b;
    double  pnum = 1;
    printf("Enter the value of A :");
    scanf("%d",&a);
    printf("Enter the value of B :");
    scanf("%d",&b);
   
    pnum=power(a,b);
    
    printf("%d Raised to the Power of %d is %lf", a, b, pnum);
    return 0;
}
double power(int a, int b)
{
    double pnum=1; 
    int i;
    if (b > 0)
    {
        for (i = b; i>0; i--)
            pnum = pnum * a;
    }
    else if(b < 0)
    {
        for(i=b; i<0; i++)
             pnum=pnum/a;
    }
    return pnum;
}

Output - Program To Calculate Power Using Function

Enter the value of A :5                                
Enter the value of B :3                                    
5 Raised to the Power of 3 is 125.000000
