|c format specifier for size_t||0.92||0.6||1583||9|
Is there a format specifier specifically for size_t? The other length modifiers that are available are hh (for char ), h (for short ), l (for long ), ll (for long long ), j (for intmax_t ), t (for ptrdiff_t ), and L (for long double ). See §184.108.40.206 (7) of the C99 standard. Yes, there is. It is %zu (as specified in ANSI C99).What is a format specifier in C++?

The correct way to print size_t variables is use of “%zu”. In “%zu” format, z is a length modifier and u stand for unsigned type. The following is an example to print size_t variable. In the above program, a variable of size_t length is declared and initialized with a value.What does the sizeof operator do in C++?
The sizeof operator returns a type of size_t. The proper format specifier for that type is %zu. If you use %lu to print a size_t, it may or may not work, depending on whether or not size_t is larger than a long. If size_t is larger, you have undefined behavior, if not the behavior is well defined.
