Thread: Question about pointers #2

Remember that 'string' is a bad variable name to use, as it is already part of the std namepsace of the header <string>. You should use a more descriptive name too, such as:

Code:

char *lpchString; //Indicates that the variable is a pointer to a char

>You should use a more descriptive name too, such as: <snip godawful hungarian notation>
The name string or str or anything similar is silly anyway. A more descriptive name can easily be found, such as buffer or line or name, so that it more readily depicts how the string is going to be used. The code makes it obvious that the simulated array is to be used as a C-style string, the name should tell readers what the string is logically going to be used for.

>Yes.
No, it won't. Mixing new[] with delete is undefined, delete[] should be used instead.

A null pointer doesn't have to be address 0, it just has to be some value that would not be a valid pointer.
