Int main()=why always right int with main(). what does it mean
@Pavan0001
main is a function like any other so it has to have a return type.
A lot of programmers used to use void main( ) in programming and it worked until C++ standards made it compulsory to use int main( ).
The reason is simple. If you run the program , the return value returned by the main( ) is used an exit code for the program and is thus essential. We generally return 0 from main( ) to show success.
