Question

I am writing a program that needs to do a bit of arithmetic.

Here’s what I have so far:

#include <stdio.h>
int main(void){
    double h, x, n;
    printf("enter h > ");
    scanf("%1f", &h);
    printf("enter x > ");
    scanf("%1f", &x);
    /* here's where I believe I'm encountering an error */
    n = x/h;

    return 0;
}

so let’s say I put in h = 0.01 with x = 0.25, I should get n = 0.25/0.01 = 25 right?

I’ve tried typecasting:

n = (float)x/(float)h;

but it doesn’t work…

The problem is probably due to scanf.
I suggest using fgets instead.
But try:

int main(void){
    float h, x, n;
    printf("enter h > ");
    scanf("%f", &h);
    getchar();
    printf("enter x > ");
    getchar();
    scanf("%f", &x);

    n = x/h;

    return 0;
}
