How do you format an unsigned long long int using printf? My number is 8 bytes wide and its value is 285212672l A normal number is 0 I assume this unexpected result is from printing the unsigned long long int How do you printf() an unsigned long long int?
c - Is it valid to use %lu in a format string for printf where PRIu32 . . . printf("%lu\n", i); I’d suppose yes, since I can see no reason why not However, if yes, then this would remove the need for existence of these macroified specifiers like PRIu32, so I figure I’d better ask The reason I’m asking it is that I’d like to create a format string for printf dynamically, and it’d be hard to allocate space for this format string if I don't know the size of
printf - Difference between %zu and %lu in C - Stack Overflow What is the difference between %zu and %lu in string formatting in C? %lu is used for unsigned long values and %zu is used for size_t values, but in practice, size_t is just an unsigned long

Whats the difference between %ul and %lu C format specifiers? But using %lu solved the issue Actually, rather than focusing on the problem and the line of codes, I want to know about the difference between %ul and %lu Maybe I could figure out what's wrong Searching doesn't give me something useful (except that "they are different") Any explanation or link reference is appreciated
