Thanky you,
I'll will try those programs.

For static structures like the above, the compiler can potentially
figure out out-of-bounds scenarios. Try turning up the warning level.
There are tools out there for detecting run-time out-of-bounds access
attempts. BoundsChecker and GlowCode come to mind as examples of
run-time tools. Lint is a static code checker. But expect to pay
through the nose for those tools. VC++ will detect buffer overflows in
debug builds but usually only runs the check code every so often (making
it more difficult to determine where the overflow occurred).
