    }
    std::cout << "YOU LOST ALL YOUR MONEY!!";
    return 0;
}

Tried to use functions with this one, but it failed, may be because of int in function is not the same as the int in the main.
Also need help in that department.

srand(...) should be called only once at the top of main.

See this:

http://www.cplusplus.com/reference/cstdlib/srand/?kw=srand

for what you need to include.
