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.

(Numerical) Write a program that tests the effectiveness of the rand() library function. Start by initializing 10 counters to 0, and then generate a large number of pseudorandom integers between 0 and 9. Each time a 0 occurs, increment the variable you have designated as the zero counter; when a 1 occurs, increment the counter variable that’s keeping count of the 1s that occur; and so on. Finally, display the number of 0s, 1s, 2s, and so on that occurred and the percentage of the time they occurred.
(Conversion) a. Write a C++ program to convert meters to feet. The program should request the starting meter value, the number of conversions to be made, and the increment between metric values. The display should have appropriate headings and list the meters and the corresponding feet value. If the number of iterations is greater than 10, have your program substitute a default increment of 10. Use the relationship that 1 meter = 3.281 feet. b. Run the program written in Exercise 6a on a computer. Verify that your program begins at the correct starting meter value and contains the exact number of conversions specified in your input data. c. Modify the program written in Exercise 6a to request the starting meter value, the ending meter value, and the increment. Instead of the condition checking for a fixed count, the condition checks for the ending meter value. If the number of iterations is greater than 20, have your program substitute a default increment of (ending value - starting value) / 19.
AHPA #9:A Gas Station• You have been asked to create a C program to manage the gaspumps at a gas station. The station has four pumps connectedto four tanks with capacities: 100, 75, 50, and 150. Every timea car fills up it takes 10 gallons. You’ll know that a car hasarrived because the carArrived function will return with apump number. After a car has filled up, print out the currentcontents of all four tanks.• Write a C program that can track each of the four tanks. Updatethe amount of gas remaining in a tank when a car fills up.When a tank gets to less than 20 gallons of gas remaining,make a call to request a refill truck visit the station(refillRequest). This will cause the tank to berefilled automatically
In C++ Language (please use hint) : Write a function which will swap its arguments if the first argument is greater than its second argument, but will not interchange them if the first argument is samller than or equal to the second argument. The function should return 1 if a swap was made, and 0 otherwise. (Hint: Make sure to use call by reference.) Write also a short test driver (i.e. a main() invoking your function).
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.
In C++, please write a program according to the instructions and all the criteria. Thank you. Instruction Write and test a function that returns a copy of its string parameter with no repeated characters. The functions ignore case when they compare letters. The functions return strings whose letters are upper case. Write 2 versions of the function: string remDups(const string& original); void remDups(const string& original, string& nodups); Suppose the original string is “Myrtle has big feet” The function returns MYRTLE HASBIGF Test the functions thoroughly. Criteria compile, run, test the test program compiles, runs, and calls both versions of the function without crashingthe test program tests the functions thoroughly function parameters and returns one function has one constant string reference parameter and returns a stringone function has one constant string reference parameter, one string reference parameter and returns void. function operations the function removes…
C Program Functions using Pointers Create a function modify that accepts an integer and divides the integer by 2 if it is even. If the integer is odd, add one and divide it by 2. The function does not return anything. In the main function, write a program that asks for an integer input and call the modify function by passing in the reference of that variable as a parameter. An initial code is provided for you. Just fill in the blanks. Input 1. One line containing an integer input Output Enter a number: 5 Before: 5 After: 3
Instructions: In Basic C Language In the code editor, you are provided with a main function that asks the user for an integer input and passes this value to a function called, getFactorial() The getFactorial() function has the following description: Return type - int Name - getFactorial Parameters - one integer Description - returns the factorial of the passed integer Your implementation should be RECURSIVE and you should not use any loops Input #include<stdio.h> int getFactorial(int); int main(void) { int n; printf("Enter n: "); scanf("%d", &n); printf("Factorial of %d is %d", n, getFactorial(n)); return 0;} int getFactorial(int n) { // TODO: Implement this recursive function} Output should be: Enter n: 3 Factorial of 3 is 6
C PROGRAM Reverse + Random Formula In the code editor, there's already an initial code that contains the function declaration of the function, computeReverseNumber(int n) and an empty main() function. For this problem, you are task to implement the computeReverseNumber function. This function will take in an integer n as its parameter. This will get the reverse of the passed integer and will then compute and return the value: result = (original_number + reverse_of_the_number) / 3 In the main() function, ask the user to input the value of n, call the function computeReverseNumber and pass the inputted value of n, and print the result in the main() with two (2) decimal places. SAMPLE: Input n: 20 Output: 7.33 Input n: 123 Output: 148.00
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…
Q9/Write a program in c++ that inputs a three-digit integer, separates the integer into its individual digits and prints the digits separated from one another by three spaces each by using functions. For example, if the user types in 429, the program should print: 4 2 9
5.Write a function called isValidOddDigits that takes an integer number and returns 1 if the number represents valid code and 0 otherwise. Valid code is determined according to the following rule: The sum of the digits must be odd number. For example, the number 324 is valid because the sum of the digits is 9, which is odd. However, the number 114 is not valid because the sum is 6 which is not odd. Write a complete C++ program with a function named CountDiv5 that accepts two integer numbers n1 and n2 where n1 must be less than n2.The function should return the number of integers divisible by 5 between n1 and n2 inclusively. Write a function ConvertToCelsuis which takes a Fahrenheit temperature and return its equivalent in Celsius. C = 0.556 × (F-32)
