product of an integer and a fraction
Hi there,
I am trying to make a simple program that will calculate 25% of 480.
When I put the code in using num1 as 480 and num2 as .25 it calculate a number of 0 for the product.
What is the trick to this? what am i doing wrong?
this is the code i am using:
#include <stdio.h>
int main(){
/*declare variables for each integer */
int num1, num2, product;
num1 = 480;
num2 = .25;
product = num1 * num2;
printf("25 percent of $%d is $%d.\n",num1, product);

you don't want to use integers.
assigning 0.25 to an integer will make that integer be equal to zero.

i'll be sure to look those up. i'm posting in the beginners post because obviously i'm a beginner... this is the first programming I've ever done. its for my intro course at university....so thank u
no worries dude.
have a read of the first section of this: http://www.cplusplus.com/doc/tutorial/
it should all become clear.
