Answer to Question #163767 in C++ for Anonymous

Question

Create a program that will compute:

1. The area and circumference of a circle. Prompt the user to enter the radius. Use 3.14159 for pi.
2. The area and the perimeter of a rectangle. Prompt the user to enter the length and the width.

• Use the plan you created last week. If need be revise your pseudocode and algorithm to match expect output and Mimir test cases. 
• Once again desk check your pseudocode and algorithm.
• Do not allow for invalid input.
• Allow for positive values only.
• Format to 3 decimal places

 

• Name file main.cpp
• To Mimir submit: .cpp file
• Submit your pseudocode and desk check along with your code to Mimir in a separate file
• Pseudocode and desk check should be in the format of a pdf, picture, or notepad.
• Include your name, date at the top of the code as a comment.
• Restate project assignment question as a comment
• Include detailed comments throughout your code.

Answer 1

#include <iostream>
#include <cmath>
using namespace std;
void circle (int radius) {
    const float pi = 3.14159;
    cout << "The area of the circle: " << pi * pow(radius, 2) << endl;
    cout << "The circumference of the circle: " << 2 * pi * radius << endl;
}
void rectangle (int length, int width) {
    cout << "The area of the rectangle: " << width * length << endl;
    cout << "The perimetr of the rectangle: " << 2 * (width + length) << endl;
}
int main () {
    int w, l;
    float r;
    cout << "Enter radius of the circle: "; cin >> r;
    circle(r);
    cout << "Enter length of rectangle: "; cin >> l;
    cout << "Enter width of rectangle: "; cin >> w;
    rectangle(l, w);
    return 0;
