- 1. Complete an algorithm, code and compile the following program. Save the program as mathTutor.py. Math Tutor You will be creating a math tutor program that can be used for young children to practice their math skills. The program will be driven by the following menu: See Rules Practice Math Exit If the user chooses (1) from the menu, the following rules will be displayed: This program will help you practice your math skills. First, you will choose Addition, Subtraction or Multiplication. Next, you will choose a level. Level 1 will give you problems with single digits and Level 2 will use two-digit numbers. Then, you will choose how many math problems you would like to complete. After you have completed all your problems, you will be given a score. You can play as many times as you want. Have fun!!

The user is presented with a guessing game and must enter their guess as to which number the computer is "thinking of" (the randomly generated number between 1 and 15). The user is limited to five guesses. If the user guesses the correct number within the five guess limit, they win. If the user does not guess correctly within the five guess limit, they lose the game. Following each user input, the output must say "your guess of _ was too low. try again" or "your guess of _ was too high. try again" or "you guessed it!" Instructions: The program must make use of passing by value and reference, if-else, defined constants, and use of the random number generator/seeding. The seed function srand() should only be called once in main. The point is to demonstrate use of multiple functions (those aforementioned) even though this could be accomplished with a much…arrow_forwardUsing C++ programming language: Use the if construct to check a range.

Here is the program logic specification: There are six assessment activities Quiz1, Quiz2, Quiz3, Quiz4, Lab Journal, Major Assignment and Final Exam. The four quizzes are worth 5 marks each, the Lab Journal is worth 10 marks, the Major Assignment is worth 30 marks and the Final Exam is worth 40 marks. The algorithm for computing the total mark for the unit is: Total Mark = Quiz1+Quiz2+Quiz3+Quiz4+Major Assignment+ Lab Journal + Final Exam The following screenshot shows a successful test run:arrow_forward
