## FAQs on What are Functions ? Video Lecture - Mathematics (Maths) Class 11 - Commerce

 1. What is a function in programming?
A function in programming is a block of code that performs a specific task. It can be called multiple times within a program to execute the same task, allowing for code reusability and modularization.
 2. How do functions help in organizing code?
Functions help in organizing code by breaking it down into smaller, manageable pieces. By dividing a program into functions, each responsible for a specific task, it becomes easier to understand, debug, and modify the code. Functions also promote code reusability, as they can be called from different parts of the program.
 3. What are the advantages of using functions in programming?
There are several advantages of using functions in programming: - Code reusability: Functions can be called multiple times, reducing the need to rewrite the same code. - Modularity: Functions allow for the division of a complex program into smaller, more manageable modules. - Readability: Well-defined functions enhance the readability of code by providing meaningful names and encapsulating specific tasks. - Debugging: Functions make it easier to locate and fix errors since issues can be isolated to specific functions. - Collaboration: Functions promote collaboration among developers as they can work on different functions independently.
 4. Can functions return values?
Yes, functions can return values. When a function is called, it can perform a calculation or process and return a value back to the caller. This returned value can be used for further computations or stored in a variable.
 5. How are functions different from variables?
Functions and variables are different in their purpose and behavior. - Variables store and manipulate data values, while functions execute a specific task or set of instructions. - Variables have a single value associated with them, whereas functions can have multiple lines of code to perform complex operations. - Variables can be changed and updated throughout the program, while functions are typically defined once and called multiple times. - Variables are used to store and retrieve data, while functions are used to perform actions and calculations.
