Question

what is a function in c

Answer 1

A function is a small set of instructions designed to operate on its given input (parameters or arguments) and perform some action or return some output.

Answer 2

Answer:

The function is a group of declarations that together perform a task. Every C program has at tiniest one function, which is main ( ), and all the smallest programs can define additional purposes. A function declaration tells the compiler about a function's name, return type, and parameters.

I think I have made my point.
