    Unhappy Reference to a pointer

    I am unable to get "reference to a pointer".
    Here:

    char*p = "hello";
    char*&k = p;


    while creating reference to a pointer why we have to write *&k , why not &*k?

    I recommend you:
    1. Change your code writing style to use spaces like
      Code:
      char* p  =  "hello";
      char*& k  =  p;
    2. Use Code tags while posting code snippets.

    Now about your question:
    Code:
    char a;	// character a
    char* p;	// p is a pointer to a character
    char& r;	// r is a reference to a character
    char*& rp;	// r is a reference to a pointer to a character
    char&* pr;	// r would be a pointer to a reference to a character

    That's the syntax for a reference.

    An int reference would be
    int&, so a char* reference is char*&.

    Re: Reference to a pointer

    #include <stdio.h>

    void main()
    {
    int x = 10 ;

    3 = x;

    }

    When we run the above program compiler error :"left operand must be l-value" occur , why it's telling about left operand while in the
    program 3 is on RHS... ????

    1. Return to the list of threads in C++ (Non Visual C++ Issues) forum.
    2. Access the Post New Thread page through the button-like link.

    You are mistaken: 3 is on the left hand side.
