In any reasonably modern C implementation, "%zu"is the correct way to print a value of type size_t: printf("sizeof (int) = %zu ", sizeof (int)); The "%zu"format specifier was added in the 1999 ISO C standard (and adopted by the 2011 ISO C++ standard).How to print size_t variables in Python?

size_t is an unsigned type so you still need to use 'u' as the format type as well as the 'z' length modifier. – CB Bailey Jun 2 '09 at 15:20 Also, the 'z' modifier is a C99 addition to printf, so its not strictly a standard C++ feature.
