2013年3月25日 · MS Visual Studio didn't support %zu printf specifier before VS2013. Starting from VS2015 (e.g. _MSC_VER >= 1900) %zu is available. As an alternative, for previous versions of Visual Studio if you are printing small values (like number of elements from std containers) you can simply cast to an int and use %d:

If size_t exists shouldn't zu also be available in printf? size_t existed at least since C89 but the respective format specifier %zu (specifically the length modifier z) was added to the standard only since C99. So, if you can't use C99 (or C11) and had to print size_t in C89, you just have to fallback to other existing types, such as:

2022年7月29日 · 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. CppCheck complains about it, but both work for both types in my experience.

And "%zu" works for all values of type size_t, including those outside the range of the corresponding signed type. Finally, POSIX defines a type ssize_t in the headers <unistd.h> and <sys/types.h>.

2020年6月20日 · I've seen a couple questions about how to convert a PFX to a cert file, but I need to go the other way. I have two files: bob_cert.cert bob_key.pem I'd like to convert them to a single .pfx file....

There is absolutely no reason to do any of this. You're attempting to shave off each digit from the integer backwards, convert each digit to a character manually, append each digit one at a time to the string builder, before reversing the whole thing to get the original ordering back.
