I guess the algo would be something like this:

open file

while it's not in EOF,
    read in a statement (*)
        if ths statement contains required var
            print it, along with line number for reference

close file

Function to read in a statement:

empty buffer

repeat
    read in a character
        if the character is a semi-colon,
            terminate buffer
            return
        if the character is an open-brace '{'
            search for keywords in buffer so far to indicate that this
            is a statement and not a function (if, while, etc.)
                if it is a statement
                    terminate buffer,
                    return
                if it's a function
                    empty buffer,
                    continue searching
        if the character is a close-brace '}'
            ignore it,
            continue searching
        add character to buffer

Try coding it, I dunno how well it'll work.
