decimal places

I created a program that converts centigrade to farehenheit, and I want to only print the answer to two decimal places. I can probably leave it as it is, since the problem doesn't ask to be formatted that way, but if get a problem that involves money, I would like to know how to do it.

Here's the problem, and the language is c:

Code:

/* This program converts Centigrade to Farenheit.

Written by: zero2

*/



#include <stdio.h>



int main (void)

{

/*Local Definitions*/

float cent;

float far;





/*Statements*/

printf("Enter Temperature in Centigrade\n");

scanf(" %f", &cent);

far = 32 + (cent * 1.8);

printf("Temperature in Centigrade: %f\nTempreture in Farenheitt: %f\n", cent, far);

        return 0;

}

/* main */



/* Results 



Enter Temperature in Centigrade

37

Temperature in Centigrade: 37.000000

Tempreture in Farenheitt: 98.599998

Press any key to continue */

Read the documentation for printf, it will do exactly what you want.

Thanks a-j, I just had to put the formating in the printf statement like such:

Code:

printf("Temperature in Centigrade: %3.2f\nTempreture in Farenheitt: %3.2f\n", cent, far);

I probably should of mentioned that I was using visual studio, and am just a beginner at this.

I kind of knew that it had something to do with the printf statement, but I kept putting it in the wrong place, before % sign, which gave me some strange answers.
