Answer 2

Your code for me is not clearly readable.

1. First of all modify the three scnafs into one:

scanf("%d %d %d", &d1.day, &d1.month, &d1.year);

instead of
scanf("%d",& d1.day);
scanf("%d",& d1.month);
scanf("%d",& d1.year );

Check user input
printf("Date 1:%d/%d/%d\n\n",d1.day, d1.month, d1.year);
printf("Date 2:%d/%d/%d\n\n",d2.day, d2.month, d2.year);
-- ----------------------------
2. If there are cases in switch with the same result
try to write it as

case 1 :
case 3 :
case 5 :
case 7 :
case 8 :
case 12 : DAYS+=d3.month*31;
break;
-- ----------------------------
3. then your code is complicated.
try to split it into functions.
for example for your switch statement create a function to return days

int findDays(date d3){
switch (d3.month ){
case 1 :
case 3 :
case 5 :
case 7 :
case 8 :
case 12 : d3.day=31+d3.day;
break;

case 4 :
case 6 :
case 9 :
case 11 : d3.day=30+d3.day;
break;

case 2 : if ((( d3.year % 4 ==0 ) && (d3.year%100 != 0)) || (d3.year%400 ==0)){
d3.day=29+d3.day;
} else {
d3.day=28+d3.day;
}

break;
} // emnd of switch

return d3.day;

}

Continue as above and I think that you will find your error

Prokopios Poulimenos oh there is a lot of infos in your comment that i didn't knew about thanks man. I will try fix what i can

Answer 4

Prokopios Poulimenos is it ok not to put "/" in the scanf ?
edit. : my bad. i thought that printf. a scanf xD

Answer 5

Yes, you can do it
scanf("%d/%d/%d", &d1.day, &d1.month, &d1.year);

But then your input should be in format dd/mm/yyyy
