Roulette in C++ – 7th C++ Practice Assignment

Roulette in c++ is a popular casino game that we will be implementing in this practice assignment. If you don’t know what Roulette is, it’s a casino game, where the player chooses to place bets on either a single number or a range of numbers, the colors red or black, or whether the number is odd or even.

This implemented version of roulette in c++ is only basic, the program flow follows as this

1. The Game starts
2. The user places how much he/she wants to bet
3. The user chooses either to bet on a specific number, black or red, or an odd/even number
4. The game will generate the random number
5. The game will decide whether the player wins or loses
