Write a function power that computes x raised to the power y for integer x and y and returns double type value.

#include<stdio.h>

#include<conio.h>

#include<math.h>

#include<string.h>

void main()

{

    int x,y;

    double power();

    clrscr();

    printf("Enter value of x : ");

    scanf("%d",&x);

    printf("Enter value of y : ");

    scanf("%d",&y);

    printf("%d to power %d is = %f\n",x,y,power(x,y));

    getch();

}

double power(x,y)

int x,y;

{

    double p;

    p=1.0;

    if(y>=0)

       while(y--)

           p*=x;

    elsewhile(y++)

           p/=x;

    return(p);

}
