Sure, work your way through these warnings.
It helps if you have a decent compiler with lots of warnings enabled.

The problems are
1. You have an over reliance on global variables.
2. None of your functions take parameters or return results.
3. Your exit function must be called something else to avoid problems with the real exit function.
4. Your variable naming is vague, non-descriptive - and therefore unhelpful.
5. Your bill() function has an out of bound memory access.

All those 'variable shadows variable' issues mean you're updating one variable, while you might be thinking you're updating another.
FYI, the variable with the nearest scope is the one that always wins.

Before you next try and write a 500+ line program only to find out it doesn't work, read this.

Thank you so much , can you help fixing them , i m new in c , and dont know all these :(

i u sing dev c++ and its not showing such errors , out is coming but worng

Step 1: Learn the name and version of your compiler.
Step 2: Learn where to find the build log (The output of the compiler during compilation and linking)
Step 3: Learn how to turn up warnings on your compiler using the IDE interface.

If by dev c++, you mean this one -> Bloodshed Software - Dev-C++, then it's obsolete (web page last updated 05 Feb 2003).

If you want something up to date, which works the same then use Dev-C++ download | SourceForge.net

I told you what was wrong.
You can start by fixing the names of all your variables so there are no shadows.

If by "help" you mean, will you rewrite 500 lines of code for me, then the answer will always be no.
