A method is a procedure or function in OOPs Concepts. Whereas, a function is a group of reusable code which can be used anywhere in the program. This helps the need for writing the same code again and again. It helps programmers in writing modular codes.
- A method also works the same as that of function.
- A method is defined inside a class. For Example: main() in Java
- A method can be private, public, or protected.
- The method is invoked by its reference/object only. For Example: If class has obj as an object name, then the method is called by:
- A method is able to operate on data that is contained within the class
- Each object has it’s own method which is present in the class.
- A function is a block of statements that takes specific input, does some computations, and finally produces the output.
- A function is defined independently. For Example: main() in C++
- By default a function is public.
- It can be accessed anywhere in the entire program.
- It is called by its name itself.
- It has the ability to return values if needed.
- If a function is defined, it will be the same for every object that has been created.
Below is the program to illustrate functions and methods in C++:
