line 13: exit is the name of a standard c or c++ function. Give that variable a different name.


line 1163: don't call main() anywhere in your program. That function should only be called by the operating system. If you need to repeat the code that is in main() then put a loop in that function.


Next time post line numbers with those error messages so that we know where to look in your program.
