[Dev-C++] Memory

[Robson B. <rob...@su...>]

Hi coders,

I have a question that does not want to shut up! When i code a program, do i
have to delete all variables before exiting the main function or does the
operating system cares of free all the memory allocated? If i do not delete
the variables before main function and use the program several times, may it
cause the system memory to be unavailble?

Any input welcome!

Thanks!
