Hidding the code

[CosminPerRam]

As you may know, all programs and games which arent open source the code is hidded and if you try to open it it will give you some strange symbols, how i can do that to my files too? Thanks in advance and i hope you will understand me.

I am exactly sure I understand the problem, but let me have a guess.

I guess you opened an executable file in an editor ?
To do the same compile your program and open the .exe file in an editor and you should also see lots of strange symbols.

A compiler can inject "debugging symbols" into the binary that make it easier for a debugger to match the executable with source code. Your "users" won't have the source code, so that is not a huge concern, but you can tell the compiler to not inject those symbols, to "decrease the size of the binary".
