difference between exit () and return () functions

difference between exit () subroutine termination function and return () function

In the main function we usually use return (0), which returns a value in this way.

But this is a form that is limited to void main () in a non void case.

Exit () is typically used in subroutines to terminate a program, and the following program automatically ends the hop operating system.

But when you use exit in main, whether or not the value returned by main is defined as void is valid, and exit does not need to consider the type, exit (1) is equivalent to return (1)

#include <iostream>
#include <string>
using namespace Std;
int main ()
{
    Exit (1);//equivalent to return (1);
}
