Directions: Write a program that will perform a casino game using C or C++. Provide comments in the codeexplaining everything. See above deliverable instructions. Requirements: A menu will first appear asking the user to choose which game they would like to play. The userwill be able to choose between blackjack and roulette.The blackjack game will only play one hand at a time against the dealer. If the dealer and the user have the same,then it’s a draw. If you do not know how to play blackjack, then you might need to research the game.The roulette game will ask the user what numbers they would like to bet on. If the random number is chosen, thenthe user wins.Each game should ask the user how much money they would like to bet before the game starts. The user shouldhave a starting amount of money, once the user loses their money, the user will then need to stop playing.

A complex number is a number in the form a+bi, where a and b are real numbers and i is √(-1) The numbers a and b are known as the real part and imaginary part of the complex number, respectively. You can perform addition, subtraction, multiplication, and division for complex numbers using the following formulas: a + bi + c + di = (a+c) + (b+d)i (addition) a + bi − (c + di) = (a−c) + (b−d)i (subtraction) (a + bi) * (c + di) = (ac−bd) + (bc+ad)i (multiplication) (a + bi) / (c + di) = (ac+bd) / (c2+d2) + (bc−ad)i / (c2+d2) (division) You can obtain the Absolute Value for a complex number using the following formula: |a + bi| = √(a2 + b2) A Complex number can be interpreted as a point on a plane by identifying the (a,b) values as the coordinates of the point. The absolute value of the complex number corresponds to the distance of the point to the origin, as shown in the example below. (1) Design a class named Complex for representing complex numbers Include…
