Thread: getting incorrect output

hi i'm doing an exercise from C Primer Plus. the problem is this:

In the U.S. system of volume measurements, a pint is 2 cups, a cup is 8 ounces, an
ounce is 2 tablespoons, and a tablespoon is 3 teaspoons. Write a program that requests a
volume in cups and that displays the equivalent volumes in pints, ounces, tablespoons,
and teaspoons. Why does a floating-point type make more sense for this application than
an integer type?

this is the code i wrote:

Code:

#include <stdio.h>

int main(void)
{
    float pint, cup, ounce, tablespoon, teaspoon;
    pint = 2 * cup;
    cup = 8 * ounce;
    ounce = 2 * tablespoon;
    tablespoon = 3 * teaspoon;
    printf("How many cups? ");
    scanf("%f", &cup);
    printf("pints: %f -- ounces: %f -- tablespoon: %f -- teaspoon %f \n", pint, ounce, tablespoon, teaspoon );
    return 0;
}

and this is the output:

How many cups? 25
pints: 0.000000 -- ounces: 0.000000 -- tablespoon: 0.000000 -- teaspoon 0.000000

i fixed this with this code:

Code:

#include <stdio.h>

int main(void)
{
    float pint, cup, ounce, tablespoon, teaspoon;
    printf("How many cups? ");
    scanf("%f", &cup);
    pint = cup / 2;
    ounce = cup / 8;
    tablespoon = ounce / 2;
    teaspoon = tablespoon / 2;
    printf("pints: %f -- ounces: %f -- tablespoon: %f -- teaspoon %f \n", pint, ounce, tablespoon, teaspoon );
    return 0;
}

When I try to run this program in Visual Basic 2013 it only asks for the first line flashes then leaves the screen how can i get it to pause to show it all printed? I have tried the ("PAUSE") but that doesn't work.
