Study Notes
Understanding Methods in Programming
- A method, also known as a function, is a reusable block of code designed to perform a specific task or calculation.
- Methods help organize code, allowing for clearer structure and easier debugging.
Purpose of Functions in Programming
- Functions improve code reusability, enabling developers to write code once and call it multiple times.
- They enhance modularity, making it easier to focus on individual tasks within a program.
Syntax for User-Defined Functions
- The typical syntax for defining a user-defined function includes the function keyword, followed by the function name, parameter list in parentheses, and a block of code enclosed in braces.
- Example format:
returnType functionName(parameterList) { // function body }
Purpose of the Parameter List
- The parameter list allows functions to accept input values, enabling dynamic behavior based on the provided arguments.
- It facilitates the passing of data to the function, which can then be processed and used within the function body.
Use of the 'void' Keyword
- The 'void' keyword is utilized in function declarations to indicate that the function does not return a value.
- Functions declared as void are typically used for actions where the output is not needed, such as printing data or modifying global variables.
