What is a functional programming language? How is it different from imperative languages?<|im_end|>
<|im_start|>assistant
Functional programming is a programming paradigm where computation is treated as the evaluation of mathematical functions and mutable data is avoided. It is different from imperative programming, which relies on changing the state of a program and modifying data. Functional languages like Haskell, Lisp, Scheme, and ML promote immutability, no side-effects, first-class and higher-order functions, recursion and declarative approach. Meanwhile imperative languages like C, C++, Java, Python focus on giving a sequence of statements that change a program state and how the code should execute step-by-step.<|im_end|>

Certainly, here are a few resources where you can learn more about functional and imperative programming languages:

•"Introduction to Functional Programming" by Richard Bird, available for free on the website of the University of Cambridge
•"Functional Programming in Scala" by Paul Chiusano and Rúnar Bjarnason, available for purchase on Amazon
•"Functional Programming for the Object-Oriented Programmer" by Brian Marick, available for free on the website of the Association for Computing Machinery
•"The Little Schemer" by Daniel P. Friedman and Matthias Felleisen, available for purchase on Amazon
•"Programming in Haskell" by Graham Hutton, available for purchase on Amazon
•"The Structure and Interpretation of Computer Programs" by Harold Abelson and Gerald Jay Sussman, available for free on the website of the Massachusetts Institute of Technology
•"Elements of Functional Programming" by Jean-Paul Tremblay and Paul G. Sorenson, available for purchase on Amazon
•"Learn You a Haskell for Great Good!" by Miran Lipovaca, available for free on the website.
•"Programming with C#" by John Sharp, available for purchase on Amazon
•"The C Programming Language" by Brian W. Kernighan and Dennis M. Ritchie, available for purchase on Amazon
These resources cover a wide range of functional and imperative programming languages and provide a good starting point for further learning and experimentation.<|im_end|>
