What are the errors?

I've seen a load of errors that are just syntax etc.

e.g.

• no function type for main - int main(void) etc. This might not be necessary I suppose but the compiler will wonder what the return type should be
• switch statement requires braces '{' around case statements
• I assume 'stremp' is actually 'strcmp'
• INFORMATTION type is not declared

I wont continue cos this will cause all sorts of problems.

If I've not called this correctly then sorry, but most of what I've seen in the code is simple syntax.

If it's old C, then main() { } is valid, due to the "implicit int" mis-feature. This has since been dropped, so C99 will complain about that.

i shall re- read my code again thanks guy's for spotting out the mistake .
