What is the difference between main()function in C and C++

Answer 1

The valid signatures for both languages are:

int main(void);
int main(int argc, char* argv[]);

In the case of C++, there's no need to state void within the function header/prototype.

While some compilers may except void return type for main(), it has never been part of the language standard. Neither in C nor C++.

Answer 4

A good thing to know : In C++, by default, you can ONLY return an int value. But in some cases with modifications, you can return other values, but never a void.

Answer 5

in c ...if simply nothing is written it assumes by default void (void main())....and we can also use int main() and then return some interger....however in c++ we can not have void main...also if simply writes main ...it assumes by default int...

Answer 6

Main function of C may be void, when returns nothing. In C++ main can not be void. It will return int value. In c main function, we do declare all variables together in beginning of the program.

Answer 7

C++ programs also start with the main () function. The execution of every program starts with the main () function. The programming rules for c++ are same as c.
Exceptionally, while working with class and objects in c++ we write the main () function at the end of the program to create an object which is in no way possible in c language!
