How many arguments can a return statement have

in this case what will it return and why

Just one, read your book.

But in case you don't have a book...

return can only be passed one value. However it could be an array if they are of the same type.

Buy, Beg, Borrow or Steal one.

But in case you don't have a book...

return can only be passed one value. However it could be an array if they are of the same type.

That depends on what sort of "array". A locally declared array, such as int ret_arr[10]; cannot be the return value, nor can a C-style string. On the other hand, C++ strings or STL containers (vectors, for example) can be returned.
