Tcc compileOnce

[Davider]

Hi,
The following code is executed multiple times and the variable values will continue to stack. How to reset it?
I need to recompile the code every time it is executed
PS: I have some difficulties in understanding C language programming and pointer variables

Thank you in advance for any suggestions and help!
