Write a C program to calculate power of a number.
/* calculate power of a number */
int power(int x, int y) {
int res = 1, i;
/* x^0 = 1 */
if (y == 0)
return 1;
/* find x^y value */
for (i = y; i > 0; i--) {
res = res * x;
}
return res;
}
int main() {
int x, y, result;
/* get the input from the user */
printf("Enter the value for x and y(x^y):");
scanf("%d%d", &x, &y);
/* find x^y value */
result = power(x, y);
/* print the result */
printf("%d ^ %d = %d\n", x, y, result);
return 0;
}
Output:
jp@jp-VirtualBox:~/$ ./a.out
Enter the value for x and y(x^y):2 4
2 ^ 4 = 16
Enter the value for x and y(x^y):2 4
2 ^ 4 = 16
