Methods of the Class

Methods in a class are essentially just functions that are defined within the class. They are used to define the behaviors or actions that objects of the class can perform.

Methods often manipulate the attributes of the class or perform operations that are relevant to the objects.

Implementation of Methods Outside the Class

Methods can be defined outside the class declaration using the scope resolution operator (::). This is often done to separate the declaration in the header file from its implementation in the source file. Here's how you would do it:

Example


              1234
            
class Example {
public:
    void Method();
};

It's not mandatory to create two distinct files for this purpose; you can achieve it within a single file, and in certain situations, it proves to be beneficial.

main


              12345678
            
#include <iostream>

class Example {
public:
    void Method();
};

void Example::Method() { std::cout << "Method was called" << std::endl; }

Feel free to tackle the task using the method of your preference. But the common good practice is to separate declaration and implementation.

Tarefa

Swipe to start coding

You are working with a Square class and need to add methods to compute its dimensions.

Implement area() and perimeter() methods inside the Square class.
Create an instance of the class, assign a value to its side, and call both methods to get the results.
