What is return type of getchar(), fgetc() and getc() ?
In C, return type of getchar(), fgetc() and getc() is int (not char). So it is recommended to assign the returned values of these functions to an integer type variable.
char ch;
while ((ch = getchar ()) != EOF)
{
putchar (ch);
}

Here is a version that uses integer to compare the value of getchar().
int in;
while ((in = getchar ()) != EOF)
{
putchar (in);
}
