Functions or methods in programming are blocks of code that perform a specific task. They are designed to be reusable, allowing you to call them whenever you need to execute the same functionality without having to rewrite the code. Functions typically take input parameters, perform some operations, and then return a result.
When you call a function in your code, you are essentially instructing the program to execute the code within that function. This helps in organizing your code, making it more modular, and easier to maintain. Functions can also return values that can be used in other parts of your program.
Overall, functions or methods in programming provide a way to encapsulate logic, promote code reusability, and improve the overall structure of your codebase.
