Thread: Floats

Hi,
Im new to programming and have found myself doing it because it is a requirement for my engineering course. I was wondering if there is anyway to limit the amount of decimal places displayed in the program when using a float or a double. Because I only need 3 decimal places shown not 6.

Code:

#include <stdio.h>

int main(void)
{
     float f = 1.23456789;
     printf("%.3f\n", f);

     return 0;
}

printf and scanf format codes

Are you expecting like this?

Code:

#include<stdio.h>
main()
{
        float a=12.343434;
        printf("%.3f",a);
}

Okay, got 3 places now. Thanks for the help.

One other question. In my program I am asking for input of date in form of dd/mm/yy, what declaration would I need to make in order to store a value in that form.

You can use string declaration
char *ptr="dd/mm/yy"

not a pointer since you want it to be variable so i would just say

char date[10];

Thanks, ill try it tonight
