What does Test& Test::func () mean?

Question

I have been learning 'this' pointer. And everywhere I see is this format of calling class and accessing the member function and constructor. What does it mean?

This may help to introduce what a reference type is ...

https://en.m.wikipedia.org/wiki/Reference_(C%2B%2B)

Anyways, I think the first return statement should be `return s;` rather than `return x;`. Variable <x> is an unknown there : )

Answer 2

Is that all there is? maybe a complete block of the code can improve clarity.

As I see it, it is a definition of a member function named `func`. The fuction is a member of a class named `Test`, and it returns a reference to an object instantiated from the `Test` class itself.

Answer 3

Ipang What does "it returns a reference to an object" mean?

Answer 4

Ipang here is the code snippet.
class person
{
char name[20];
float age;
public:
person(char *s, float a)
{
strcpy(name, s);
age=a;
}
person & person::greater(person &s) //returns a reference to an object. what does it mean?
{
if(s.age>=age)
return x;
else
return *this;

}
