I'm creating a UNO game for a project for school, and I need some help.
Basically what I did so far was create an array that has all 100 elements stored into it. I then have a line of code that "shuffle" this deck. If you run the program as it is, it will ask you to name 4 players and then it will give you 7 random cards for those players.
I need help with creating a loop that will take the 7 random array values and then store them for the player's hand. Each player will need a hand so that will result in 4 arrays.
The other thing that I will need help with is adding x amount of cards to the array. and a separate thing that will remove the card from the array when the player types it out. (check code)
Any help in the right direction will be appreciated.

I would have a player object which contains a hand member (like std::vector<Card> Hand;) which takes 7 random vector elements and adds them to each players (create 4 player objects) hand. Though that would require rewriting a lot of your code lol
Why vectors instead of arrays? Read below.

Unless your professor has given you a certain specification for this project, I would rather use std::vector<type> instead of std::array. I don't use arrays often in C++ so I'm probably not even going to be any help to you here but I know for sure that with std::vector you can add (push_back) and delete (erase) elements from the vector itself since it is a dynamic array in a sense unlike arrays which have a fixed size after compiling (if you're familiar with C#, C++ vectors work similar to a C# list).

For your "playerLoop" function, you have declared the reverse boolean and initialised it to false.
This means that every time the function is called, the while loop won't execute because the value is already false.

I have changed the code slightly since then. A member in my group did that.

This helps. There is nothing specific that was assigned for this project, it is a final project for the class. I don't know much about vectors, because it is an intro class and we havent gotten that far. I plan to do some research on them. If you don't mine, can I pm you when I get some research done?

I'm not the best at explaining this sort of stuff but yeah sure thing.
