Please answer this in c++ asap A very successful cinema director named "Chef" decided to solve the problem. When a customer wants to buy a ticket, the clerk at the ticket window asks the visitor if he or she needs a rest area, and if so, which one: left, right, or both. We know that in the audience they are expected to appear, their L needs a left-handed position, their R needs a right one, Z does not need a single one and B needs both. Your job is to count the number of people who can attend the show. In the theatre there are N rows with each M seat. There is only one lounge between the two adjacent seats. Seats at the beginning and end of the row have two armrests Input 1 223211 Output: 4
Using C Language: Write a program that consists of 2 guessing game. The first game: It is a guessing game in which the computer picks a specific number from 1 to 10, then the user guesses the number chosen by the computer and has ten attempts, and in each attempt the chosen number by the computer changes. The second game: A guessing game. The computer also chooses a three-digit number, for example: 950 and you have ten attempts to predict the number chosen by the computer. For example, the user types 390, the computer will tell him that the first digit is wrong, the second digit is correct, but it is not in the correct location, and the last digit, which is 0, is correct. And the user makes repeated attempts to find the correct whole number
Q2: Write a program in C++ to read ten students' name and degrees then calculate the average degree for each student if all his degrees above or equal 50. If a student has a degree less than 50, do not calculate the average degree for him. then print the result as shown below: Ahmed Ali Degrees= Math Drawing. 66 66 Ali Assad Degrees= Math Drawing........ 40 50 Name Result Average Ahmed Ali Pass 66 Ali Assad Not pass Note: each student has 7 classes.
Write a C++ program that calculates the Volume of a Triangular Prism. The main function asks the user to input a (i.e., length of the triangular prism), b(i.e., base length of the triangular prism), and h(i.e., the height of the triangular prism. Then the main function calls another function to calculate the volume of that triangle prism. Finally, the main function displays the volume of the triangle prism. Recall that Volume of a Triangular Prism =1/2 abh
Write a program in c++ for determining if a year is a leap year. In the Gregorian calendarsystem you can check if it is a leaper if it is divisible by 4 but not by 100 unless it is also divisible by 400.For example, 1896, 1904, and 2000 were leap years but 1900 was not.Write a program that takes in a year as input (as a command line argument) and prints the string "{year} was a leap year'' if true and "{year} was not a leap year'' if false.Note: background on leap year https://en.wikipedia.org/wiki/Leap_yearHere is a possible example call to the program .\isleapyearc 1896 output: 1896 was a leap year Here is a negative example call to the program .\isleapyearc 1897 output: 1897 was not a leap year with note You are supposed to get the year from command line arguments. You are getting it from stdin c++ language
Write a C++ program that computes the rental fees of N cars; N is the first input by the user. For each car the user should input the car category and the number of rental days. Note that an 11% VAT tax is added to the car rental fees. At the end the program should output the following information: The daily income (the sum of all the cars rental fees). The percentage of clients who rented cars for more than 10 days.
In C++ , Write a program for a Bookstore to take an order from a customer, calculate how much to charge a customer based on his/her order, and display a receipt. The store sells only three books, designated by their authors: Cervantes ($41.25 each), Homer ($15.85 each), and Shakespeare ($30.50 each). Your program is to work as follows: Display a welcome message (e.g., “Welcome to the Bookstore!”) Prompt the user for his/her first name Prompt the user to input the number of books by Cervantes s/he wants Prompt the user to input the number of books by Homer s/he wants Prompt the user to input the number of books by Shakespeare s/he wants Compute the total amount due, including a 10% sales tax Display amount due Ask the user how much money s/he will pay Display a receipt listing the name of the user, the quantity of each item ordered, the total cost of the order, and the amount the user will have left after paying Execution of the compiled program should appear roughly as follows…
Write a C++ program to register students. Ask whether a student must be registered. If Y, ask whether the course to register for is BScIT? If Y display the amount of R15000.00 with a message that this is the course fee for this year. If not BScIT display R12000.00 with a message that this is the course fee for this year. Keep on registering students until there are no more students to register. Answer N to the question whether another student must be registered. Display the following: The total number of students registered and the total number of students registered for BScIT. The total amount received for all the registrations and the total amount received for the BScIT student registrations. Hints:  You need TWO constant variables: bsc_fee and other_fee  You need 4 counter variables: total_number, bsc_number, total_amt, bsc_amt  Counter variables MUST get the value of 0 when you declare them.  You need TWO char type variables: answer, bsc_course If you can you the preparation…
Write a C++ program that takes a 4-digit number from user as and input and displays all the combinations of those digits.Sample Output: Enter number: 5321Possible Combinations are:5321, 5312, 5231, 5213, 5123, 5132 3521, 3512, 3251, 3215, 3125, 31521523, 1532, 1253, 1235, 1325, 1352 2513, 2531, 2153, 2135, 2315, 2351
Write a C++ program that asks the user how many schools are participating in this year's competition. You can assume that this number is at least 3. Then, ask for each school's name and call another function; this separate function should ask the user for 3 scores and return the average of those scores. Once you have gotten each school's name and average score, print out everyone's score and then who won gold, silver, and bronze. Your C++ program MUST include at least 1 array, at least 1 loop, and at least 1 function other than int main. If you are having difficulty determining gold, silver, and bronze, you can determine just who gets gold and still receive a high grade. You do not have to do any input validation. You must display all decimals with 3 digits after the decimal point. You can also assume that there will be no tied scores.

In C++ using endl; Write a program that can be used to calculate the federal tax. The tax is calculated as follows: For single people, the standard exemption is $4,000; for married people, the standard exemption is $7,000. A person can also put up to 6% of his or her gross income in a pension plan. The tax rates are as follows: If the taxable income is: Between $0 and $15,000, the tax rate is 15%. Between $15,001 and $40,000, the tax is $2,250 plus 25% of the taxable income over $15,000. Over $40,000, the tax is $8,460 plus 35% of the taxable income over $40,000. Prompt the user to enter the following information: Marital status If the marital status is “married,” ask for the number of children under the age of 14 Gross salary (If the marital status is “married” and both spouses have income, enter the combined salary.)

Write a C+ program that prompts the user to enter a positive integer between 100 and 9999 pnclusive). The program shall validate the number, the number is valid, the program shall transform the number (construct a new number) as followes • If it is a 3-digit number, the program reverses the number. For example, the number 345 will be transformed to 543. • if it is a 4-digit number, the program exchanges the second and third digits. For example, the number 4527 wil be transtormed to A257. Sample input/output Enter a positive integer between 100 and 9999: 345 The number 345 is transformed to 543 Enter a positive integer between 100 and 9999: 4527 The number 4527 is transformed to 4257 Enter a positive integer between 100 and 9999: 78
