what is main? can someone give a simple explanation

Answer 1

Hey there,
I would like to know "main" in which context

If in C or C++
It's the entry point of the c program
This is the first function to be called once the program starts..
A c program strats in main and ends in main (unless program crashes)

Answer 2

The main is the heart of your application. It is the first thing to run and is responsible for calling other functions.
