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…
DateType keeps only the integer representation of the month,day, and year. When a month is wanted in string form, the string iscalculated. An alternate approach would be to add a string field tothe date and calculate and store the string representation in theInitialize function. Which methods would have to bechanged? Would this change make the use of an if statement tofind the appropriate string more or less attractive? Write the code in C++for this if statement.

Write a function definition called AddPoints that has one integer parameter called points & the function returns an integer. (in C). Inside the function, declare, ask, & get an integer from the user (the bonus points), add the bonus points to points thst are copied into the function & return the sum.
For parameter passing, call by constant reference is for the function if the value of the actual parameter isn't changed and does no copying. Group of answer choices True False

If it is not prime, output the factors ("the number <> has the factors <>, <>, <>, <>") 10 - proper functioning 10 - style (esp good naming and breakdown to functions)
Using C++ Using your own creativity, make a set of function templates that have these features: This function must return a value. A function template with 1 template parameter, T. And, any other parameters you want. and then another function template but this time with 2 template parameters, T1 and T2. And, any other parameters you want.

Suppose that you have the following recursive function written in C++. I've intentionally written the function so that it doesn't use descriptive names for anything, though that's obviously not a good design practice, but I aim not to bias your understanding of the techniques you'll be using by assuming anything about what the function's goal is; to stay "on task" here, you should resist the temptation to try to figure that out first. void kaboom( const std::vector& v, std::vector& w, unsigned int i) { if (i < w.size()) { int q = 0; for (int j : v) { q += j; } w.at(i) - kaboom(v, w, i + 1); } = q; } 1. Using the techniques from our discussion of the Asymptotic Analysis of Recursion, write a recurrence that describes the time required to run the following call to kaboom for two vector v and w whose sizes are the same. Use the variable s in your recurrence to denote that size. kaboom(v, w, 0) 2. Using the repeated substitution technique, reduce the recurrence to a closed form, then give…
