Question

#include <stdio.h>
#include <math.h>


int main (void)
{
    float inches;
    printf("Enter the number of inches\n");
    scanf("%f\n",&inches);


    float feet;
    float cm;
    float yards;
    float meter;

    feet = 12 * inches;
    cm = 2.54 * inches;
    yards = 36 * inches;
    meter = 39.37 * inches;

    printf("Amount in feet: %f\n", &feet);
    printf("Amount in cm:   %f\n", &cm);
    printf("Amount in yards: %f\n", &yards);
    printf("Amount in meters: %f\n", &meter);




   getchar();

   return 0;

}

I’m using Dev c++

Is the problem i’m problem I’m working on in C. Basically enter in a number in inches then print amount in cm,yards,meters and feet. This is giving me 0.0000 or something for all of them or actually the time it is up. I can’t keep the screen up and I thought that was the purpose of getchar() but I must have been mistaken. Any help is great. Thanks!

EDIT 1

What about as far as keeping dev c++ on the screen instead of closing out after I put stuff in? I am also having to put 2 values in before it returns in anything when the screen pops up? Why??

Answer 1

Two problems:

1. The usual problem with using scanf(), in that it leaves the newline after the number unread and the following read operation (the getchar() here) reads it.
2. You shouldn’t pass pointers to printf(), but the actual values.
