How can I start coding cheats?

I tried several CSGO Bases, most of them gave compiler errors , Am I missing something(except brain)? All the Source Codes are broken, Some of them compiles but CSGO Crashes as soon as I inject or run .exe , I don't want to C+P stuff and post here there, I just wanna use them myself.. Can Anyone help me or guide me? Just Ignore if I'm asking a silly question
Is there any way that I get a VCJ Project in which Procmem shit is already there and All I need to do is add functions ?
