getchar() question

I have seen in different text/source code that a variable that will get the getchar() result is declared in some code listings as int and in other code listings as char.
Which is the proper approach?
Thank you.

Hi! Here's a start to the proper approach:

Code:

---

int main(void)
{
        // Your code here


      return 0;
}

The type of variable that stores the result of getchar should match the return type of getchar (int). Read through the documentation here for the details: getchar(3): input of char/strings - Linux man page.
