Question : Write a program to find difference of two dates in years,months and dates. Dates are in valid range and first date falls before second.

 //To find difference of two dates in years,months and dates, Dates are  in valid range and first date falls before second.

#include <stdio.h>
int main()

    if(m2==3)
    {
        if (y2%100!=0 && y2%4==0|| y2%400==0) // Checking leap year
            d2+=29;

scanf("%d/%d/%d,&d1,&m1,&y1");

and

scanf("%d/%d/%d,&d2,&m2,&y2");

are wrong you must read the manual of scanf().

The first argument is the format string "%d/%d/%d" and you must pass each address after: &d1, &m1, &y1.

scanf("%d/%d/%d", &d1, &m1, &y1);
scanf("%d/%d/%d", &d2, &m2, &y2);

You should verify the return value of function:

if (scanf("%d/%d/%d", &d1, &m1, &y1) != 3) {
  fprintf(stderr, "Something go wrong!");
  return 1;
}
