Can anyone tell me why this program to find x to the power of n and sin(x) is wrong? Its a basic C program. I'm still learning.

Question

#include<stdio.h>
#include<math.h>
#include<conio.h>
main()
{
double r,x,y,z,n;
clrscr();
printf("Key in values for x, n and sin(x): \n");
scanf("%f%f%f", x, n, z);
r = z* 3.14159/180.0 ;
y = sin(r);
printf("sin(%f) = %f \n" , z, y);
y = sqrt(x);
printf("sqrt(%f) = %f \n" , x, y);
y = pow(x,n);
printf("%f to the power %f = %f\n", x,n, y);
getchar();
}

Answer 1

You declared double types use %lf.

Correct way :
scanf("%lf %lf %lf", &x, &n, &z);
