It doesn't. Your call to scanf("%c", &q) is doing exactly what it's
supposed to do.
To find out what it's supposed to do, read the documentation for
scanf().
You're almost certainly better off using a different method to read
input. A common technique is to use fgets() to read a line at a time,
then use sscanf() to parse the string. (This can have its own
drawbacks; fgets() either leaves the newline character in the input
string, or truncates the line if it's too long.)

We must do something. This is something. Therefore, we must do this.
