Overloading the ++ operator to incriement an iterator

[new2cpp]

Hello,

I am currently creating a sqaure list and one of the requrements is to overload the the pre and post ++ operator.

Ive tried overloaded the ++operator in my .hpp file to increment an interator. But when calling the ++operator it does not call the overloaded code and just uses the default.

iterator& operator ++ () {  // pre-increment 
        std::list<int>::iterator i = list_Values.begin(); 
        advance(i,1); 
        return &*i; 
    } 
 
    iterator operator ++ (int) { // post-increment 
        std::list<int>::iterator i = list_Values.begin(); 
        advance(i,1); 
        return &*i; 
    }

What do you mean the default? There is no default...

Also the point of the post-xxx operator is that it makes a copy, does something to the original, then returns the copy.

Well when I say default,I mean that it seems to do the ++ operator in the standard library instead of what I created.

I'm not sure if my code is 100% right but I hope i'm close.

There is no such type name as iter in std::list class.

Well looking at your code I can conclude that the same iterator is always used after incrrement

iterator& operator ++ () {  // pre-increment 
        std::list<int>::iterator i = list_Values.begin(); 
        advance(i,1); 
        return &*i; 
    } 

I.e. you always return begin() + 1. However I think you should get begin() + 1 after the first increment then begin() + 2 after the second increment and so on.

I tried this and when i try to incirment an iterator it doesnt get called.

All i did was

int* test;

test = sqrlst.begin();
++test;

Thank you for the suggestion..if you have any more please let me know
