Answer to Question #155875 in C++ for Rijak

Question

IN THE FORM OF PROCEDURAL PROGRAMMING;

CREATE A PROGRAM THAT COMPUTES THE AREA OF A GIVEN RECTANGLE AND A CIRCLE.

AREA OF RECTANGLE = LENGTH * WIDTH

AREA OF CIRCLE = 3.1416 * RADIUS 2

1. In procedural programming, create a function named "getArea()" with the following parameters.

a. int length

b. int width

c. int radius

Note. Use the following variable names

2. The function must have 2 main procedures which are:

Solving of the area of the rectangle (Variable name = recta)

Solving for the area of the circle (Variable name = cira)

Note. Printing the answer must be included in the function.

3. In the main() program of the source file, allow user to enter the length of the rectangle (Variable name =rectlength,) , width of the rectangle (variable name =rectwidth, and the radius of the circle (variable name = cirradius)

4. Call "getArea" function using the user input

TEST CASE #1

Length of Rectangle: 7

Width of Rectangle: 5

Radius of Circle: 5

Area of rectangle = 35

Area of rectangle = 78.54

Answer 1

#include <iostream>
#include <cmath>
using namespace std;
void getArea (int length, int width, int radius) {
    int recta; 
    float cira;
    recta = length * width;
    cira = 3.1416 * pow(radius, 2);
    cout << "Area of Rectangle: " << recta << endl;
    cout << "Area of Circle: " << cira << endl;
}
int main () {
    int rectlength, rectwidth, cirradius;
    cout << "Legth of rectangle: ";
    cin >> rectlength;
    cout << "Width of Rectangle: ";
    cin >> rectwidth;
    cout << "Radius of Circle: ";
    cin >> cirradius;
    getArea(rectlength, rectwidth, cirradius);
    return 0;
}
