    Simple Pointer Question

    Let me start by saying I am fairy new to C programming, but not programming in general.

    Say you have the code below which defines a pointer to an array of chars (a string right? heh), and then you want to assign some text to that string. From the tutorials I have read, and the coding I have tried I know this works:

    Code:
    char *name;
    name = "Reason58";
    Now given that pointers are variables which store the memory address of other variables, why is the above code acceptable? Shouldn't it be:

    Code:
    char *name;
    name = &"Reason58";
    Or something similar? Sorry for the stupid question. I have pointers like 98% figured out, just wanted to clarify that.

    Thanks.

    A "string" has the same type as a char array

    You can do this with an array
    Code:
    char arr[10];
    char *p = arr;
    char *q = &arr[0];
    So you can do this
    Code:
    char *p = "string";
    char *q = &"string"[0];

    Is a really good explanation of pointers
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
