What is need function?
Why we need functions in C a) To improve the readability of code. b) Improves the reusability of the code, same function can be used in any program rather than writing the same code from scratch. c) Debugging of the code would be easier if you use functions, as errors are easy to be traced.
Why do we use functions?
This example highlights the two most important reasons that C programmers use functions. The first reason is reusability. Once a function is defined, it can be used over and over and over again. You can invoke the same function many times in your program, which saves you work.
What are Python functions?
A function is a block of organized, reusable code that is used to perform a single, related action. As you already know, Python gives you many built-in functions like print(), etc. but you can also create your own functions.
