15.7 In-Lab Activity 7: Shapes (I/O operator overloading)
In this program, you must implement I/O operator overloading (<< and >>) to match a shape's functionality.
You must modify the following files:
Triangle.h
- Implement the declaration for the overloaded I/O operator functions.
Triangle.cpp
- Implement the calculateArea() function to find the area of the triangle.
- Implement the definitions for the overloaded I/O operator functions.
- The input function will take in two variables: The base and height (cin >> base >> height)
- Call the object's calculateArea() function after inputting the variables.
The output function will send the following to the output stream (for base = 10 and height = 20):
Triangle Object: Base: 10 Height: 20 Area is: 100
Square.h
- Implement the declaration for the overloaded I/O operator functions.
Square.cpp
- Implement the calculateArea() function to find the area of the square.
- Implement the definitions for the overloaded I/O operator functions.
- The input function will take in two variables: The base and height (cin >> base >> height)
- Call the object's calculateArea() function after inputting the variables.
The output function will send the following to the output stream (for base = 10 and height = 20):
Square Object: Base: 10 Height: 20 Area is: 200
HINT: Print newline characters after every line (endl or "\n")
