in the C++ version please suppose to have a score corresponding with probabilities at the end and do not use the count[] function. Please explain the detail when coding. DO NOT USE ARRAY. The game of Pig The game of Pig is a dice game with simple rules: Two players race to reach 100 points. Each turn, a player repeatedly rolls a die until either a 1 ("pig") is rolled or the player holds and scores the sum of the rolls (i.e. the turn total). At any time during a player's turn, the player is faced with two decisions: roll - if the player rolls 1: the player scores nothing and it becomes the opponents turn. 2 - 6: the number is added to the player's turn total and the player's turn continues. hold - The turn total is added to the player's score and it becomes the opponent's turn. This game is a game of probability. Players can use their knowledge of probabilities to make an educated game decision. Assignment specifications Hold-at-20 means that the player will choose to roll…
Write C++ Program to check whether the Given String is a Palindrome. To resolve this problem, you should write 3 void functions: inputStrings, testPalindrome and displayNumbers. • inputStrings : the aim of this function to read 7 strings from the user and insert them in array of 7 elements. testPalindrome: to check whether the given strings in the array are palindrome. • displayPalindrome: print the palindrome strings.
Please use easy logic with proper indentations and comments for understanding!. Coding should be in C++. 3. Define a class which stores up to 10 integer values in an array. The class should also define the following 4 public methods: setNumber – accepts an integer value to store in the array. The value is stored in the next available element of the array (first call to the method stores the value in element 0 with the second call storing the value in element 1.) The method returns true if there is room in the array and the integer was successfully stored. Returns false otherwise. clear – removes all values from the array so that the array can be reused. displayNumbers – displays the values currently stored in the array. getStats – determines the largest, smallest, and average of the values currently stored in the array. These values are returned to the caller via reference parameters. All methods should produce correct results regardless of the order in which…
Write in C++ 1. Define a struct for a soccer player that stores their name, jersey number, and total points scored. 2.Using the struct in #1, write a function that takes an array of soccer players and its size as arguments and returns the average number of points scored by the players. 3.Using the struct in #1, write a function that takes an array of soccer players and its size as arguments and returns the index of the player who scored the most points. 4.Using the struct in #1, write a function that sorts an array of soccer players by name. 5.Using the struct in #1, write a function that takes an (unsorted) array of soccer players and its size and a number as arguments, and returns the name of the soccer player with that number. It should not do any extra unnecessary work. 6.Define a function to find a given target value in an array, but use pointer notation rather than array notation whenever possible. 7.Write a swap function, that swaps the values of two variables in main, but use…
Zybooks C++ 1.7 LAB: Introduction to data structures labs Step 1: Producing correct output Three commented-out lines of code exist in main(). Uncomment the lines and click the "Run program" button. Verify that the program's output is: 2 + 2 = 4 Unknown function: PrintPlus2 Secret string: "abc" Submit your code for grading. Your submission will pass the "Compare output" test only, achieving 1 of the possible 10 points. Step 2: Inspecting the LabPrinter class Inspect the LabPrinter class implemented in the LabPrinter.h file. Access LabPrinter.h by clicking on the orange arrow next to main.cpp at the top of the coding window. Member functions Print2Plus2() and PrintSecret() print strings using std::cout. Step 3: Implementing CallFunctionNamed() Remove the three uncommented lines from main(). Then implement the CallFunctionNamed() function in main.cpp to handle three cases: If functionName is "Print2Plus2", call printer's Print2Plus2() member function. If functionName is "PrintSecret",…
