Develop a C++ program to calculate the area, perimeter and diagonal of a rectangle. The program should also offer the option to display the rectangle. The main flow of the program is given as follows: The user should input the length and width of a rectangle. The user can decide to display the drawing of the rectangle or not. If user indicate yes, execute user's decision. Display the calculated area, perimeter and diagonal of the rectangle. The program should repeatedly ask if the user wants to process another rectan- gle. Your program should include two functions with the following function prototypes: void drawRec(int length, int width); A function that display a full rectangle with '+'. void calcRec (int a, int b, int *area, int *perim, float *diag); A function that returns the area, perimeter and diagonal through pointer parame- ter. Sample output:

Concept explainers

Operations

In mathematics and computer science, an operation is an event that is carried out to satisfy a given task. Basic operations of a computer system are input, processing, output, storage, and control.

Basic Operators

An operator is a symbol that indicates an operation to be performed. We are familiar with operators in mathematics; operators used in computer programming are—in many ways—similar to mathematical operators.

Division Operator

We all learnt about division—and the division operator—in school. You probably know of both these symbols as representing division:

Modulus Operator

Modulus can be represented either as (mod or modulo) in computing operation. Modulus comes under arithmetic operations. Any number or variable which produces absolute value is modulus functionality. Magnitude of any function is totally changed by modulo operator as it changes even negative value to positive.

Operators

In the realm of programming, operators refer to the symbols that perform some function. They are tasked with instructing the compiler on the type of action that needs to be performed on the values passed as operands. Operators can be used in mathematical formulas and equations. In programming languages like Python, C, and Java, a variety of operators are defined.

The program should also offer the option to display the rectangle. The main flow of
the program is given as follows:
The user should input the length and width of a rectangle.
The user can decide to display the drawing of the rectangle or not. If user indicate
yes, execute user's decision.
Display the calculated area, perimeter and diagonal of the rectangle.
The program should repeatedly ask if the user wants to process another rectan-
gle.
Your program should include two functions with the following function prototypes:
void drawRec(int length, int width);
A function that display a full rectangle with '+'.
void calcRec (int a, int b, int *area, int *perim, float *diag);
A function that returns the area, perimeter and diagonal through pointer parame-
ter.

Part 1 Tom has recently started a plant-selling business, and he offers three different types of plants, namely Monstera, Philodendron, and Hoya. Each pot costs $11.50, $13.75, and $10.99, respectively, and there are 20 pots available for each plant. To minimize the workload of his employees, Tom requires a C++ program for online shopping. The program will exhibit a menu with all the available plant types. The customers can choose the plant type by entering the first letter of the plant's name (M or m for Monstera, P or p for Philodendron, and H or h for Hoya), followed by the quantity they want to buy. If the amount of pots requested exceeds the available pots, the program will display an apology message. The customers can select multiple plant types and quantities until they are ready to pay. Once they are done, the program will add a 12% tax to the total amount and display it with three decimal places. Finally, the program will print a thank you message. The program will not accept…
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.
