[prog] C problem I am unable to solve

[Dan]

Your problem may be here:

>         scanf("%c", &q);

See if it's reading the newline (Return or Enter) character as well as
the character you're looking for.

The man page for scanf says that "White space (such as blanks, tabs, or
newlines) in the format string match any amount of white space,
including none, in the input." So the solution may be as simple as
adding a newline or space to the end of the format string ("%c").
