what do i do with c++

so i downloaded c++ while trying to do some other things for something else,
anyway i've never used to before, and i have no idea what it is or what i'm doing, other then it's an apparent tool used to create hack codes...
can some1 help me with how to use it and make my own hacks? pretty please?

Its very hard.
Search on google something like " learn c++ in 21 days,"
Or find a proper coder. Which have time for you.
