Calling a specific value in a function?

Doopliss (2)
I've composed a code solely for practice, and I'm having trouble on calling a specific value in a function. Under the 'wallet' while loop, where I call the function with w+job(1), it loads the entire function rather than just adding the value of G. How can I just use the value of G, instead of loading the entire function?

Line 114: jsel = rand() % 1+4; //this generates 4 or 5
If you need to see more examples of the rand function look here: http://cplusplus.com/reference/clibrary/cstdlib/rand/

Well, I just fixed the randomizer, now all I have to do is figure out how to add g to w without activating the entire function.

Your compiler should give you warning that job() doesn't return anything, and I'm curious on what did w = w + job(1); (line 48) produce... :|

- hope you've put srand() in main() already
- float b; b = 0; can (and usually is) be declared in one line float b = 0;
