Thread: Help with C programming Mathematical Calculations

I have been doing c programming for about 3 days now and am pretty confused as to why this is not working. It basically is asking to estimate the temp inside a freezer after a certain time (t) power outage...

here is what i have so far, anyhelp is appreciated...

Code:

#include <stdio.h>
int
main(void)

{

	int time; /*time */
	int temp; /* temperature */

	
	printf("EE233 Spring 2010, P1: Power Failure Freezer Temperature Estimate."); /*Greeting */ 
	printf("How long (hours and minutes) since the power failure to the freezer?>"); 
	scanf("%d", &time); 
                temp = (4*(time*time)/( time +2))-20; /*Calculate the temperature */ 
	printf("The estimated temperature inside your freezer is %d degrees Celsius.", temp ); 


		
		return (0);
}

Not asking anyone to do this for me, just give me some hints on where to make this thing work...

Thanks for any help.
