    *char and char

    Two questions really,
    What is the difference between declaring *char Name, and char Name, and what are the advantages and disadvantages of using either declaration?
    Thanks.

    I suppose you meant :

    char* Name and char Name

    The one with the asterisk(*), is a pointer to a char, which can hold the address of another char variable.

    The one without the asterisk(*), is a normal char variable which can hold characters.

    To clarify, both char* and char variables hold data, the difference is that the data for the char* variable, must be the address of a normal char variable.

    ok, so do these two declarations have exactly the same affect?

    char *FirstName="Dene", char FirstName[]="Dene\0";

    Same effect, but remember that the pointer can also point somewhere else.

    Eg.
    Code:
    char*  ptr;
    char    Name[]      = "TestName";
    char    Surname[] = "TestSurname";
    
    ptr = Name;
    cout << ptr;
    ptr = Surname;
    cout << ptr;
    btw you don't need to put the \0 in the initial string declaration.
