    format specifier (precision) in strings

    I was getting confused over the use of precision format specifiers for strings.
    Like we use
    printf("%4.2d",somevar);
    to talk about decimal places,
    what does it mean in case of a string as in
    what does
    printf("%4.2s",somestringvar);
    mean?

    It means nothing. Strings don't have decimal points.

    EDIT: Oops, I was wrong. The precision specifies the maximum number of characters to print. The left hand side is the minimum number of characters to print (any fewer characters than this will print padding)

    All problems in computer science can be solved by another level of indirection,
    except for the problem of too many layers of indirection.
