    What do you mean by "this"
    Store the 4 characters in an int in some way?

    Say
    Code:
    int floogle = 't'<<24 | 'h' << 16 | 'i' << 8 | 's'
    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.

    >int whatevar = (int) 'this' ;
    And this is supposed to be meaningful, how?

    >I'm trying to get an intger from a string.
    Be more specific. You can get an integer from a string many different ways, it depends on what you want to do with it.
    My best code is written with the delete key.

    Hi,

    Do you mean something like this?
    Code:
    union aryint
    {
         char chrs[4];
         int    x;
    };
    union aryint ai;

    ai.chrs[0] = 't';
    ai.chrs[1] = 'h';
    and so on.

    Then

    printf("The int is %d",ai.x);


    Is this what you want?

    Another wild attempt at answering the non-specific question:

    When all else fails, read the instructions.
    If you're posting code, use code tags: [code] /* insert code here */ [/code]
