    struct accessing member question

    I have jumped into this C stuff and I'm trying to grasp
    an understanding of structures and pointers and all that fun.
    I'm on my second month of this stuff. I feel I'm moving very slow but
    I'm not giving up. At any rate hello and it's nice to meet everyone.
    I couldn't find help on the FAQ's and if it's there then I reckon it still didn't click.
    My question is:
    why doesn't this work: (should be enough code for the discussion here)

    struct woman {
    int Height;
    int tits;
    char hair[7];

    struct woman wife = {
    }; ="green";

    structs_learn.c:39: error: incompatible types in assignment

    I can access and change types int but not types of char.

    You cannot assign to arrays. If you want to copy strings, use strcpy.

    That's right.
    For the record here's the fix

    strcpy(, "green");

    Alternatively, you can change hair to const char* and you'll be able to assign string literals. It has its disadvantages however, as you'll notice if you experiment.

    Outside of your DOS world, your header file is meaningless.
