C++ Programming: Instructions The program in Example 5-6 implements the Number Guessing Game. However, in that program, the user is given as many tries as needed to guess the correct number. Rewrite the program so that the user has no more than five tries to guess the correct number. Your program should print an appropriate message, such as “You win!” or “You lose!”. Code Given: //Flag-controlled while loop. //Number guessing game. #include <iostream> #include <cstdlib> #include <ctime> using namespace std; int main() { int num; //variable to store the random number int guess; //variable to store the number guessed by the user bool isGuessed; //boolean variable to control the loop srand(time(0)); num = rand() % 100; isGuessed = false; while (!isGuessed) { cout << "Enter an integer greater" <<" than or equal to 0 and " <<"less than 100: "; cin >> guess; cout << endl; if (guess == num) { cout << "You win!

Lab #3 – Day CalculationBackground - Many times one needs to do calculations on dates. Programs like Excel use the number of days since 1/1/1970 when doing these calculations. We don't know enough C++ to completely do this calculation, yet, but we can make a start.Problem - You will prompt a user for a month, a day and a year. You will then tell the user how many days since January 1 of that year the input date is.For example if the user inputs a 3 for the month, a 2 for the day, and 2000 for the year the program outputs the number of days as being 62. Note 2000 is a leap year. Therefore you must test to see if a year is a leap year when doing this problem.The three rules which the Gregorian calendar uses to determine leap year are as follows:1. Years divisible by four are leap years, unless...2. Years also divisible by 100 are not leap years, except...**3. Years divisible by 400 are leap years. **** Combining rules 2 & 3: Centennial years that are not divisible by 400 are not leap…
C ++ Demonstration: Write a program that prompts the user to input three positive angle values in degrees to determine which type of triangle it is (acute, right, obtuse). TEST CASES: If a user inputs three valid angle values: Enter the first angle in degrees: 60 Enter the second angle in degrees: 30 Enter the third angle in degrees: 90 Result: You have a right triangle! If a user inputs any negative angle values: Enter the first angle in degrees: 45 Enter the second angle in degrees: 55 Enter the third angle in degrees: -80 Result: Error! Please input a positive angle value. If a user inputs values whose sum exceeds 180: Enter the first angle in degrees: 20 Enter the second angle in degrees: 70 Enter the third angle in degrees: 100 Result: Error! It is not a triangle.
Direction: Read each sentence/ situation carefully and select the BEST answer among the choices. 1. It is a Boolean expression that tells when the loop will exit. 2. The sequence that makes up the loop body may either be a block of Turbo C statements or a single Turbo C statement. 3. In Turbo C it is a reserved word. 4. Its values determine the number of times the loop iterates. 5. It is the second type of open-ended loop. Condition For Loop Statement For Do while Loop

The program is a simple calculator that prompts the user for two numbers and an operator ( +, -, *, or / ). 7 if -_name_- == '-_main__': numberOne = int(input("Enter the first number: ")) numberTwo = int(input("Enter the second number: ")) operation = input("Enter an operator (+ - * /): ") 8 The two numbers and the operator are passed to the function where the appropriate arithmetic 10 operation is performed. The result is then returned to where the arithmetic operation and result are 11 displayed. 12 # Call performOperation method here and store the value in "result" 13 For example, if the user enters 3, 4, and *, the following is displayed: 14 print(str(numberOne) + " " + operation +…
In C++ Programming, write a program that calculates and prints the monthly paycheck for an employee. The net pay is calculated after taking the following deductions: Federal Income Tax: 15% State Tax: 3.5% Social Security Tax: 5.75% Medicare/Medicaid Tax: 2.75% Pension Plan: 5% Health Insurance: $75.00 Your program should prompt the user to input the gross amount and the employee name. The output will be stored in a file. Format your output to have two decimal places. A sample output follows: Bill Robinson Gross Amount: .......................... $3575.00 Federal Tax: ................................ $ 536.25 State Tax: .....................................$ 125.13 Social Security Tax: ................... $ 205.56 Medicare/Medicaid Tax: ......... $ 98.31 Pension Plan: .............................. $ 178.75 Health Insurance: .......................$ 75.00 Net Pay: ....................................... $2356.00 NOTE: The first column is left-justified, and the right column is…

Directions: Write a program that will perform a casino game using C or C++. Provide comments in the codeexplaining everything. See above deliverable instructions. Requirements: A menu will first appear asking the user to choose which game they would like to play. The userwill be able to choose between blackjack and roulette.The blackjack game will only play one hand at a time against the dealer. If the dealer and the user have the same,then it’s a draw. If you do not know how to play blackjack, then you might need to research the game.The roulette game will ask the user what numbers they would like to bet on. If the random number is chosen, thenthe user wins.Each game should ask the user how much money they would like to bet before the game starts. The user shouldhave a starting amount of money, once the user loses their money, the user will then need to stop playing.
Drawa structured flowchart , C++, write pseudocode that describes the process of guessing a number between 1 and 100. After each guess, the player is told that the guess is too high or too low. The process continues until the player guesses the correct number. Pick a number and have a fellow student try to guess it following your instructions.
In C++ (Find the number of days in a month) Write a program that prompts the user to enter the month and year and displays the number of days in the month. For example, if the user entered month 2 and year 2012, the program should display February 2012 has 29 days If the user entered month 3 and year 2015, the program should display March 2015 has 31 days
Program Unit Score Calculator Console App Write a Python Console Application program that allows the user to enter the marks for different assessments in a unit, and computes the total mark and grade for the unit. 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:
Use C Language Airline Reservation System A small airline has just purchased a computer for its new automated reservations system. The president has asked you to program the new system. You are to write a program to assign seats on each flight of the airline's only plane (capacity: 10 seats). Your program should display the following menu of alternatives: Please type 1 for "first class" Please type 2 for "economy" If the person types 1, then your program should assign a seat in the first class section (seats 1-5). If the person types 2, then your program should assign a seat in the economy section (seats 6-10). Your program should then print a boarding pass indicating the person's seat number and whether it is in the first class or economy section of the plane. Use a single-subscripted array to represent the seating chart of the plane. Initialize all the elements of the array to 0 to indicate that all seats are empty. As each seat is assigned, set the corresponding elements of…
