    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);
    }

    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.

    HI

    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];
