    Is there a quicker way to initialise an array?

    heres my problem i am Initializing an array of 3 strings... i know how to initialize an array with one string.

    Code:
    char foobar[6] = "marry";
    however i have a 2d array, and i need to initialize 3 strings into it is the only way to so it like this.

    Code:
    char foobar[3][9] {
         {'s','i','x','\0'},
         {'t','w','e','l','v','e','\0'} 
         ........................
    };
    is there a quicker way to do this?

    Yes,
    Code:
        char foobar[3][9] = {   {"six"},
                                {"twelve"},
                                {"seven"}
                            };
    Or at runtime,
    Code:
        strcpy(foobar[0], "six");
        strcpy(foobar[1], "twelve");
        strcpy(foobar[2], "seven");

    Just so you know, you can leave off the inner braces. Most compilers warn you about this, however, and I don't recommend doing it myself; but you sometimes see other people's code that does this, and if you don't know that you can do this it can be very confusing.
    Code:
    int num[3][3] = {1, 2, 3, 4, 5, 6, 7, 8, 9};
    I'm not sure what standard this is, if any, but gcc gives a warning with -ansi, so it's probably not C89. Don't use it, it's just a curiosity.

    Your braces should match the structure of the data you're trying to initialise, if you want to be really good about it. Some compilers / tools will complain.
    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.
