int display help

Hi, im trying to write a date problem but im having a little problem.
The program will accept an int value in the form of yyyymmdd. And i want it to display only partial of the int with printf function. Is there any function to make this work or do i need to modify printf function so it only display first 4 number for year,middle 2 number for month and last 2 for day.

ex.
date();
printf("%d",year);

Thanks.

Oops, I guess I didn't read your whole post. Why don't you post the code you have tried and we will help you out from there.

The code is something like this:

Code:

---

#include<stdio.h>
int main()
{
    void date(int,int *,int *,int *);
    int x,year,month,day;
    printf("Enter a date in yyyymmdd: ");
    scanf("%d",&x);
    date(x,&year,&month,&day);
    printf("\nThe year is %d",year);
    printf("\nThe month is %d",month);
    printf("\nThe day is %d",day);
   
    return 0;
}

void date(int z,int *y,int *m,int *d)
{
    *y=(something will make it only display first 4 number)
    *m=(something will make it only display middle 2 number)
    *d=(something will make it only display last 2 number)

 }

Well, you don't want printf, then, to get integer values; you need arithmetic. Specifically, division.

Im not sure what you meant. Im only a C beginner. Care to explain more deeply?

Well, you've got an integer such as 20080101. The year part is 2008; to get 2008 from 2008xxxx you need to divide (in this case by 10000). There's not really any C involved here, just arithmetic, except of course that (1) you can do arithmetic in C and (2) integer arithmetic in C discards remainders after dividing.

Don't use local function declarations. Put them at the top of the program, below the includes or in a separate header file.
