blackjack game
Hello,
so this is a last minute call for help. Now I am pretty much a beginner, been doing programming and c++ in general for not full 2 months. I have created a very basic yet fully/sort of working BlackJack game that hits all of the criteria for my assignment. ALTHOUGH I have been given a last minute notice that I am not allowed to use std::vector - my program is made using essentially that. I am allowed to only use Structs and arrays apparently. Could someone point me in a direction to how I could change the minimal amount of this code to use arrays instead ?
