Variables and Constant

Constants and variables are widely used in mathematical equations and expressions. They are also commonly found in the domain of programming, where each language has its own way to differentiate between a constant and a variable. Since they have all sorts of applications, knowing their differences is a good place to start.

Program in C++ & Visual Studio not Studio Code Everyone has played Yahtzee... Right? There are so many better dice games, but my family likes this one the best. A YouTube video that describes Yahtzee can be found here. The basic rules are as follows: At the start of your turn you roll five normal everyday six sided dice. In the course of your turn you would choose to reroll any of the dice up to two more times. We are more concerned in this problem with the dice at the completion of your turn. This website gives a great rundown of the probabilities of Yahtzee that you will need. NOTE: You may ONLY use a set and map data structure to complete the solution to this problem Let’s see what results the dice give us using the following data structures and process: Prompt the user to enter five valid numbers (Range: One to six inclusive on both ends) Each time the user enters a valid number, “place” it into a map of integersCreate and use a set of integers with your data to…
