## FAQs on Examples: Types of Functions Video Lecture - Mathematics (Maths) Class 12 - JEE

 1. What are the different types of functions in programming?
Ans. In programming, there are several types of functions, including: - Built-in functions: These are pre-defined functions provided by the programming language itself, such as print() in Python. - User-defined functions: These are functions created by the programmers to perform specific tasks. - Recursive functions: These functions call themselves during their execution. - Lambda functions: Also known as anonymous functions, these functions do not have a name and are used for simple tasks. - Higher-order functions: These functions either take other functions as parameters or return functions as their result.
 2. How do built-in functions differ from user-defined functions?
Ans. Built-in functions are already available in the programming language and can be directly used without any additional coding. On the other hand, user-defined functions are created by programmers to perform specific tasks according to their requirements. User-defined functions need to be defined and implemented explicitly before they can be used in the code.
 3. What is the purpose of recursive functions?
Ans. Recursive functions are used when a function needs to call itself during its execution. They are particularly useful for solving problems that can be divided into smaller subproblems of the same type. Recursive functions make the code more concise and elegant, but they require careful handling of the termination conditions to avoid infinite loops.
 4. How are lambda functions different from regular functions?
Ans. Lambda functions, also known as anonymous functions, are different from regular functions in several ways. Firstly, lambda functions do not have a name and are typically used for simple, one-line tasks. Regular functions, on the other hand, are defined with a name and can have multiple lines of code. Secondly, lambda functions can be used as expressions within other functions or statements, while regular functions are defined separately and called by their name.
 5. Can higher-order functions be used in any programming language?
Ans. Higher-order functions are a concept that exists in many programming languages, including functional programming languages like Haskell and Lisp, as well as multi-paradigm languages like Python and JavaScript. However, the specific implementation and syntax for higher-order functions may vary between languages. It is important to consult the documentation or resources specific to the programming language being used to understand how to utilize higher-order functions effectively.
