In C programming language, the name of a variable is a string that can contain uppercase letters, lowercase letters, digits, or underscores. Further, the first character in the string must be a letter, either uppercase or lowercase, or an underscore. If the name of a variable is determined by its first eight characters, how many different variables can be named in C? (Note that the name of a variable may contain fewer than eight characters.)

Question 1: break phrase  Problem statement Breaking a string into two parts based on a delimiter has applications. For example, given an email address, breaking it based on the delimiter "@" gives you the two parts, the mail server's domain name and email username. Another example would be separating a phone number into the area code and the rest.  Given a phrase of string and a delimiter string (shorter than the phrase but may be longer than length 1), write a C++ function named break_string to break the phrase into two parts and return the parts as a C++ std::pair object (left part goes to the "first" and right part goes to the "second").

Code is in C++ Instructions Write a program that reads in a line consisting of a student’s name, Social Security number, user ID, and password. The program outputs the string in which all the digits of the Social Security number and all the characters in the password are replaced by x. (The Social Security number is in the form 000-00-0000, and the user ID and the password do not contain any spaces.) Your program should not use the operator [] to access a string element. Input is as follows  highlighted in bold John Doe 333224444 DoeJ 123Password My problem is with my output, i am close with the code, but i have attached what happens on my output and i cannot figure out why? You can see how it prints out multiple times but i am lost?  The terminal image is also attached. Thank you! Here is the code: #include <iostream> //include statement(s)#include <iomanip>#include <string> using namespace std; //using namespace statement(s) void getInfo(string info); //void…

In C++ please, using basic programming one coding   The main menu should show the available options: Show the roster: Displays all the player names and jersey numbers in a numbered list. Ex: 1. Susan Martinez (33), 2. Jake Smith (21), etc. Add a player: Prompts the user to type the player's full name and jersey number. Then adds the player to the roster. Remove a player: Displays the roster and prompts the user to enter the number of the player to remove. Then removes the player from the roster. Quit: Quits the program. The program should display the main menu after the user shows the roster, adds a player, or removes a player. The program only terminates when the user chooses the quit option. Data validation should be used where appropriate. Ex: The user should not be able to choose an option that doesn't exist or delete a player that doesn't exist. The roster should be kept in alphabetic order by the players' full names. Ex: If Alice Chang (9) is added to a roster with Jake Smith and…
