- 1 Write a C++ program to calculate a rectangle's area. The program consists of the following function: • getLength This function should ask the user to enter the rectangle's length, and then returns that value as a double • getWidth - This function should ask the user to enter the rectangle's width, and then returns that value as a double. getArea – This function should accept the rectangle's length and width as arguments and return the rectangle's area. • displayData – This function should accept the rectangle's length, width and area as arguments, and display them in an appropriate message on the screen. main – This function consists of calls to the above functions.2- Write a C++ function that accept one input argument only. The input could be astring, int, float or double. If the input is string, the function returns its number ofcharacters. If the input is integer, the function returns its number of digits. If theinput is float, the function returns its number of digits before the point (for example,if the number is 8502.56, the function returns 4). If the input is double, the functionreturns its number of digits before the point and its number of digits after the point(for example, if the number is 120.5654, the function returns 3 and 4). Then, write aC++ program to test your function by entering the following values: “Quiz1” forstring, -5000 for int, 9864.1 for float, and 801.651237 for double.Q13/ Write a program in c++ that asks the user to input two numbers. If the first number entered is greater than the second number, the program should print the message: "The first number is greater." Otherwise, it should print the message: "The first number is smaller." .By using functions
- Instructions: Write a program in C++ that uses 2 different functions to compute who would win in a game of Rock Paper Scissors. Each function will use different Boolean Expressions to compute who won. The Boolean Expressions can use arithmetic operators as long as the expressions result in a 1 or a 0. Both functions will take as input, 2 integers as arguments: Player_1- This can be 0, 1, or 2 Player_2- This can be 0, 1, or 2 0=Rock 1=Paper 2=Scissors The functions will return an integer value to indicate a tie or which player won Return Value 0 1 2 Meaning Tie Player 1 Won Player 2 Won Run both functions in separate loops. Output how long it took to run both functions. Note: Both functions need to take in the same exact inputs for every loop iteration.Excercise 4: Write a C++ program that converts Omani Riyals to United States Dollars. The mainfunction asks the user to input the amount of money in OMR. Then the main function calls another function to convert the amount to USD. Finally the main function displays the result.Recall that 1 OMR = 2.6USD.Tutoriel 2 Exercise 1: Write a C++ program that reads a character. If the character input is a space, print a message specifying it. If the character input is a digit, print a message specifying it. Exercise 2: Write a C++ program that reads a character. Checks whether the character variable ch stores a space or not; if it does, the number of spaces are incremented by 1.
- C++ Programming problem: Write a function that takes as a parameter an integer (as a long long value) and returns the number of odd, even, and zero digits. Also write a program to test your function.C++ program that inputs 10 integers from the user and passes them one at a time to the function is even which returns true if the integer is even and false otherwise. The program should print whether each of the integers is even or not.Question 1: Answer the following questions (a) Produce a Pseudocode and a C++ program for a number guessing game. Your program is required to guess what a number a computer has in mind (generate number using built-in Random function) between 0 - 100. The Program prompts the user to enter a number continuously until the number match with random generated number. For each input, the program tells the users whether the input is too low or too high. So, the user can choose the next input intelligently. Sample output is as below. Guess a magic Number between 0 to 100. (Random number 8) Enter your Guess: 50 Your Guess is too High Enter your Guess: 25 Your Guess is too High Enter your Guess: 12 Your Guess is too High Enter your Guess: 6 Your Guess is too Low Enter your Guess: 9 Your Guess is too High Enter your Guess: 7 Your Guess is too Low Enter your Guess: 8 Yes, you guessed the right number 8
- Using c++ write a program : Write a C++ program to calculate net pay of an employee. Input basic pay from user, and pass it to a user defined function CalculatePay(), calculate the net pay and return to main function. Calculate net pay of employee: House Rent is 35% of basic salary Medical Allowance is 10% if basic pay is more than Rs. 10000/-. It is 15%, if basic pay is less than or equal to Rs. 10000/- Conveyance allowance is Rs. 1000/- if basic pay is less than or equal to Rs. 10000/-. It is Rs. 1800/- if basic pay is more than to Rs. 10000/- Net pay is calculated by adding basic pay, house rent, medical allowance and conveyance allowance.Topic: Function with default argument value covered in Chapter 6 Write a C++ Do not use any topic not covered in lecture. There is no need for use of loop, and needs the use of only an "if/else" statement. Write exactly these 3 functions: power(x,y), print(text, number) function and the main() function. The power(x,y) function returns an integer result that is calculated by raising a number x (integer) to a power y (integer). The second argument y (exponent) of the function can not exceed 100.If the second argument exceeds 100, the function should return -1. Your power(x,y) function must be able to take either 1 or 2 integer arguments using the concept of default argument in chapter 6. Look at the main() code to deduct what the default value should be. You should call C++ pow(x,y) function in the "cmath" library in the body of your power(x,y) function to avoid doing the power calculation yourself. The print(text, number) function is the only one that does output to the console using…Write a C++ program that calculates the average of a group of test scores, where the lowest score in the group is dropped. It should use the following functions: void getScore() should ask the user for a test score, store it in a reference param- eter variable, and validate it. This function should be called by main once for each of the five scores to be entered. void calcAverage() should calculate and display the average of the four highest scores. This function should be called just once by main and should be passed the five scores. int findLowest() should find and return the lowest of the five scores passed to it. It should be called by calcAverage, which uses the function to determine which of the five scores to drop. **DO NOT USE AN ARRAY OR GLOBAL VARIABLES!!!*** YOU MUST USE THE STATED FUNCTIONS. AND INPUT VALIDATION. For FULL CREDIT DISPLAY THE LOWEST SCORE WITH GOOD OUTPUT DESCRIPTION you MUST USE function prototyping.. DO NOT ACCEPT SCORES LESS THAN 0 OR GREATER THAN…
