It is the first function that gets called when the program is executed.
Every C plus plus program that is a main program must have the function 'main'.
All C++ programs require an entry point and the main function provides that entry point.
I don't think its possible. Every C++ program must at least have the main function.
There is no such thing. You probably meant the main function. The main function is the only function that is required as it serves as the entry point of the program.
An entry point, usually main().
There is no such term as "building function" in C++.
The main function defines the entry point of an application in C.
The main function is the entry point of your application. Its primary purpose is to process command-line switches (if any) and to invoke the appropriate functions. For trivial applications the main function may be the only function, however separating blocks of code into re-usable functions make code much easier to read.
in c main function initailly called by operating system.
if you do not used main function in c program when errors are accrued
...a function call.
In C and C++, as well as in many (all?) languages, a function can be called from more than one place in a program. That's the purpose of functions - to encapsulate pieces of code that are needed in more than one place in the program.
