C++ code please (2) Implement a PrintMenu() function, which has a string as a parameter, outputs a menu of user options for analyzing/editing the string, and returns the user's entered menu option. Each option is represented by a single character. If an invalid character is entered, continue to prompt for a valid choice. Hint: Implement Quit before implementing other options. Call PrintMenu() in the main() function. Continue to call PrintMenu() until the user enters q to Quit. Ex: MENU c - Number of non-whitespace characters w - Number of words f - Find text r - Replace all !'s s - Shorten spaces q - Quit Choose an option:
INSTRUCTIONS: Write a C++ script/code to do the given problems. MOVIE PROBLEM: Write a function that checks whether a person can watch an R18+ rated movie. One of the following two conditions is required for admittance: The person is atleast 18 years old. • They have parental supervision. The function accepts two parameters, age and isSupervised. Return a boolean. Example: acceptIntoMovie(14, true) → true acceptIntoMovie(14, false) → false
In C programming, if the return type of a function is Void how can you implement assert statements? For example, Void ceasar(int n, char*x); //if char = c and n = 3 output == f how do i use assert statements as this does not work assert (caesar(3,c)==f);
Solve the problem in C++ (Anagrams) Write a function that checks whether two words are anagrams. Two words are anagrams if they contain the same letters in any order. For example, “silent” and “listen” are anagrams. The header of the function is as follows: bool isAnagram(const string& s1, const string& s2) Write a test program that prompts the user to enter two strings and checks whether they are anagrams. Sample Run 1 Enter a string s1: silent Enter a string s2: listen silent and listen are anagrams Sample Run 2 Enter a string s1: split Enter a string s2: lisp split and lisp are not anagrams
I). Write a program in c++ with class that will help an elementary school student learn multiplication. Use the rand function to produce two positive one-digit integers. The program should then prompt the user with a question, such as How much is 6 times 7? The student then inputs the answer. Next, the program checks the student’s answer. If it’s correct, display the message "Very good!" and ask another multiplication question. If the answer is wrong, display the message "No. Please try again." and let the student try the same question repeatedly until the student finally gets it right. A separate function should be used to generate each new question. This function should be called once when the application begins execution and each time the user answers the question correctly.

An example of the machine code to output "hello" is shown below. This is an example of what a machine language submission would look like: 50 00 48 50 00 65 50 00 6c 50 00 6c 50 00 6f 00 zz
***python only *** Write a function that takes two parameters, a and b, both are strings taken from "SCISSORS", "PAPER", or "ROCK, and returns True if a wins over b according to the rules of theScissors-Paper-Rock game; False, otherwise. For example, when a is "SCISSORS" and b is "PAPER", the function should return True.
