C Program - " Exception thrown at 0x0FFC0F18 (ucrtbased.dll) " getting this error while debugging

Question

I tried debugging the lines of code one-by-one and got to know that it shows the error on line " if (strcmp(takein.year, takein.year2) == 0) ".

Please check the link above. I marked the line with red box. No idea why am getting that error.

Answer 1

strcmp(takein.year, takein.year2)  

Says compare the strings store at addresses takein.year and teakein.year2.

And what do we have in takein.year and teakein.year2?

Those are just normal integers and not addresses. Here strcmp is trying to access the memory locations outside of it's allocated process memory space and that's why the exception.

Use == to compare ints.

Use strcmp to compare strings only!

---

Also what is scanf_s("%d", &takein.year2);?

I don't believe scanf_s is the standard library function. Does this code compile and gets link successfully ?

---

Also if you are using string library functions then include <string.h> though most probably the default linking library contains the function definitions of most common functions. (e.g. libc in Linux)

Answer 2

you have been fully answered by fellows, i just want to add some improvement to your code:

// global variable;
const char *months[] = {
                "January",
                "February",
                "March",
                "April",
                "May",
                "June",
                "July",
                "August",
                "September",
                "October",
                "November",
                "December"
               };


// instead of using switch case 
    printf("Date(1) : %s %d, %d\n\n",months[printer.month-1], printer.day, printer.year);

    printf("Date(2) : %s %d, %d\n\n", months[printer.month2-1],printer.day2, printer.year2);

Answer 3

strcmp(takein.year, takein.year2) is wrong, the type of takein.year and takein.year2 is int and not char*.

Replacing

strcmp(takein.year, takein.year2)

by

takein.year == takein.year2

Should do the job, but there may be other issues.
