#include <iostream> using namespace std; int main()
{
int selection;
cout << “Which formula do you want to see?\n\n”;
cout << “ 1. Area of a circle\n”;
cout << “2. Area of a rectangle\n”;
cout << “3. Area of a cylinder\n”;
cout << “4. None of them\n”;
cin >> selection; if (selection == 1)
cout << “Pi times radius squared\n”;
else if(selection == 2)
cout << “Length times width\n”;
else if(selection == 3)
cout << “Pi times radius squared times height\n”;
else if(selection == 4)
cout << “Well okay then, good bye!\n”;
else
cout << “Not good with numbers, eh?\n”;
return 0;

Math Tutor Write a program that can be used as a math tutor for a young student. The program should display two random numbers to be added, such as 247 +129 The program should then pause while the student works on the problem.

Your program should then display the final car repair bill on the computer screen. Your program should accomplish the following: 1. Prompt the user to enter the following information: a. Information about the customer (name, street address, city, state, zip code, phone number). b. Information about the customer's vehicle (make, model, year). c. Information about the work performed (brief description, labor hours needed, cost of parts). 2. Use a labor cost amount of $100.00 per hour and a sales tax rate of 7.0%. 3. Calculate the following: Variable subtotal sales tax total repair bill amount Formula subtotal = labor cost per hour * number of labor hours sales tax = sales tax rate * subtotal total repair bill amount = subtotal + sales tax 4.

Valid test score entries are between 0 and 100 inclusive. The program should display a welcome message and run everything through the "main" function. have the ability to enter several test scores (try a loop) and print out the total score, as well as, the average score. continuously ask for test scores until the number 99.9 has been entered. test for valid entries and the value 99.9. If a test score is valid, the program should add the current score to the total score and update the number of test scores by one (+1), otherwise it displays an error message. Note : This assignment involves the use of a while loop and if-else decision making controls. You CANNOT use the reserved keywords break and continue for any portion of this program or any program for that matter throughout this course.arrow_forwarddef area(side1, side2): return side1 * side2s1 = 12s2 = 6 Identify the statements that correctly call the area function.

- Guessing game: Read a number until it's equal to a chosen number (first it can be a hard-coded constant or #define, or you can check rand() later). In case of wrong guessing help the user by printing whether the guessed number is to small or too big. ( in C language)arrow_forwardBackground: Game Rules The rules to the (dice) game of Pig: You will need 2 dice. To Play: a. The players each take turns rolling two die. b. A player scores the sum of the two dice thrown (unless the roll contains a 1): If a single number 1 is thrown on either die, the score for that whole turn is lost (referred to as “Pigged Out”). A 1 on both dice is scored as 25. c. During a single turn, a player may roll the dice as many times as they desire. The score for a single turn is the sum of the individual scores for each dice roll. d. The first player to reach the goal score wins unless a player scores higher subsequently in the same round. Therefore, everyone in the game must have the same number of turns.
