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. • get Area - 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.

(Statistical) In many statistical analysis programs, data values considerably outside the range of the majority of values are simply dropped from consideration. Using this information, write a C++ program that accepts up to 10 floating-point values from a user and determines and displays the average and standard deviation of the input values. All values more than four standard deviations away from the computed average are to be displayed and dropped from any further calculation, and a new average and standard deviation should be computed and displayed.
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…

Give solution in C ++ Language with secreenshoot of source code. Part 1 Write a function that inputs two integers in main() function and passes the integers to a function by reference. The function swaps the value. The main() function should display the values before and after swapping.Temp= Variable A;Variable A= Variable B; Variable B= TempPart 2Write a function that takes an integer n as parameter and returns the sum of its digits. For example, the program should display 9 if the user enters 135.
Write a C++ Program that calculates the area and perimeter of an upright rectangle.Create a struct Point that has two double values, x and y. Write a function that asks the user for a Point.Call that function twice, once to get the bottom left corner of a rectangle, and once to get the top right corner.Write another function that takes two Points and returns area and perimeter. Print out the area and perimeter.Given two points (x1, y1) and (x2, y2), the formulas to compute perimeter and area are as followsPerimeter = 2 ∗ (abs(x1 − x2) + abs(y1 − y2))Area = abs(x1 − x2) ∗ abs(y1 − y2)
IN C programming Write a function that will take an integer as an argument and return the factorial of the integer. Then write another function that will take two integers as arguments and then return the ratio of the factorials of the first argument with the second one. You need to make two calls to the first function inside the second function to find the factorials of the numbers.
write a C++ program. Write a program that calculates and displays the average of a group of test scores, all integers, after the lowest score in the group has been dropped. There are six test scores in the group. The program must contain only the following functions in additionto the main:• void getScore should ask the user for a test score, store it in a referenceparameter variable, and validate it. This function should be called by the mainfunction once for of the six scores to be entered by the user.• double calcAverage should calculate and return the average of the five highest scores. This function should be called just once by the main function, and should be passed the six scores. Use pass by reference to receive the lowest test score.• int findLowest should find and return the lowest of the six scores passed to it. It must be called by the calcAverage function, which uses it to determine which of the six scores to drop.• void displayResults should be called by the main function…
Write a C program that gets a string from the user and counts total number of digits in that string. Assume that the size of your string is 10. Use isdigit() function to check whether the character is digit or not. For example: isdigit(„a‟) returns 0 (false), isdigit(„3‟) returns true(1).Please remember that you need to include <ctype.h> for isdigit() library functionSample Run:Enter your string: cng230There are 3 digits in your string.
Write a C program that computes and prints the area of a rectangle given its length and width. Your program should contain and use the following functions: Description: prints the description of the program. This takes no argument and returns no value. Input: asks the user for an input value. This function returns the value asked from the user. ComputeArea: computes the area of the rectangle. This takes two arguments, length and width, and returns the computed area. Output: displays the input length and width and the computed area. This takes three arguments – length, width, and computed area – and returns no value. The content of your main function should look like this: int main() { int length, width, area; Description(); length = Input(<supply necessary arguments>); width = Input(<supply necessary arguments>); area = ComputeArea(<supply necessary arguments>); Output(<supply necessary arguments>); return 0; }…
