Write a program that asks for the length and width of two rectangles. The program should tell the user which rectangles has the greater area, or if the area are the same.
We do not write code here.
If you post your code, or have questions on how to code, we'd be glad to help review your code or help you debug.
Also, as there are many programming languages, it would help to specify the language that you are suppose to use.
#include <iostream>
using namespace std;
class Rectangle
{
private:
int width, height;
public:
Rectangle(int width=0, int height=0) : width(width), height(height) { }
int getWidth() {
return width;
}
int getHeight() {
return height;
}
};
istream& operator>> (istream& is, Rectangle& r) {
is >> r.width >> r.height;
return is;
}
ostream& operator<< (ostream& os, Rectangle& r) {
os << r.getWidth() << " " << r.getHeight();
return os;
}
Rectangle operator+ (Rectangle& r1, Rectangle& r2) {
int w = r1.getWidth() * r2.getHeight() + r2.getWidth() * r1.getHeight();
int h = r1.getWidth() * r2.getHeight();
return Rectangle(w, h);
}
Rectangle operator- (Rectangle& r1, Rectangle& r2) {
int w = r1.getWidth() * r2.getHeight() - r2.getWidth() * r1.getHeight();
int h = r1.getWidth() * r2.getHeight();
return Rectangle(w, h);
}
bool operator< (Rectangle& r1, Rectangle&r2) {
return r1.getWidth() * r2.getHeight() < r2.getWidth() * r1.getHeight();
}
bool operator== (Rectangle& r1, Rectangle&r2) {
return r1.getWidth() * r2.getHeight() = r2.getWidth() * r1.getHeight();
}
int main() {
int w, h;
for (int i=0; i<3; i++) {
cout << "Enter width and height of the first rectangle: ";
cin >> w >> h;
Rectangle r1(w,h);
cout << "Enter width and height of the second rectangle: ";
cin >> w >> h;
Rectangle r2(w,h);
if (r1 == r2)
cout << "The area of both rectangles are the SAME!" << endl << endl;
else if (r1 > r2)
cout << "The area of the first rectangle is LARGER!" << endl << endl;
else
cout << "The area of the first rectangle is SMALLER!" << endl << endl;
}
return 0;
}
To create a program that compares the areas of two rectangles, you can follow these steps:
1. Start by defining a function to calculate the area of a rectangle:
- The area of a rectangle is calculated by multiplying its length by its width.
- The function should take the length and width as parameters and return the calculated area.
Here's an example implementation in Python:
```python
def calculate_area(length, width):
area = length * width
return area
```
2. Next, prompt the user to input the length and width of the first rectangle using the `input()` function.
- The `input()` function allows you to get user input from the console.
- Store the input values as variables.
```python
length1 = float(input("Enter the length of the first rectangle: "))
width1 = float(input("Enter the width of the first rectangle: "))
```
3. Repeat the same process to get the length and width of the second rectangle from the user.
```python
length2 = float(input("Enter the length of the second rectangle: "))
width2 = float(input("Enter the width of the second rectangle: "))
```
4. Call the `calculate_area()` function twice, passing the length and width values for each rectangle.
- Store the calculated areas in separate variables.
```python
area1 = calculate_area(length1, width1)
area2 = calculate_area(length2, width2)
```
5. Finally, use conditional statements to compare the two areas and provide the desired output.
```python
if area1 > area2:
print("The first rectangle has a greater area.")
elif area1 < area2:
print("The second rectangle has a greater area.")
else:
print("Both rectangles have the same area.")
```
That's it! You have successfully programmed a solution that compares the areas of two rectangles based on user input.
