    format specifiers quick question

    Can someone please tell me what the following format specifier does exactly? I understand what the specifiers in general mean, and how to use them , but I have never seen this one before

    printf("%1X",x & 0x01 << j ? 1 : 0) ;

    I get that the big X means unsigned hex, but what does the number in front of it mean?

    Most format attributes can be mixed and matched between flags, you can find details here so I don't have to retype it all.
    My best code is written with the delete key.
