It is supposed to update the balance after every purchase, it only updates the original balance

You update them using =.

balance = balance - 20;
std::cout << "your new balance is " << balance << '\n';

The first line can be shortened to balance -= 20;

tidal scarab
#

instead of balance - 90 do balance -= 90

#

balance -= 90 subtracts 90 from the balance and returns the value

;compile -includeiostream

int balance = 100;
std::cout << (balance -= 90);

Doing std::cout << "your new balance is " << (balance -= 20) << '\n'; works too, as nevemlaci said, but it's kinda cursed

Is there a safer way to do what system("CLS") does
