Void is the return type. When a function/method is defined with void it means it doesn't return any value to the calling function.

Answer 3

"Void function does not return any value "- What does this actually mean?

It means that if you have a function

void f(....) {...}

then when doing

x = f(...);

x gets the value of Null. Not void, but Null, absence of data.
