why do we use..........Return 0

Answer 1

Technically, in C or C++ main function has to return a value because it is declared as "int main" which means "main function should return integer value or data type"
It's good practice to use it.

Answer 2

it means that the compiler has compiled the program normally, if there is any other value other than 0 it means it has compiled abnormally.

Answer 3

main is a function where the program begins. it had to report the OS how the program is executed.

Answer 4

It acts as an error code. 0 means no error.

Answer 5

return 0 is used to terminate the main function

Answer 6

It tells the compiler every thing is okay.

Try " return 3" and see what happens

Answer 7

Answer 8
