Hello everyone
On the top of page 68 just under the code we have this sentence:
The sizeof() function returns a value of type size_t, for which %zu is the correct placeholder token.
I’m not sure what ‘type size_t’ stands for.
JR
size_t is just an alias (another name) for the unsigned long type.
Also, calling sizeof () a function is an error; sizeof () is not a function, it is a unary operator.
Thank you ibex10
I am grateful for you fast answer.
However, I am puzzled by your second point you made about the sizeof() is a unary operator and not a function.
According to the book here the sizeof() IS a function! The sentence below is a direct quote from the top of page 68
Take a look at the book and tell me what you think.

That’s an oversight.
If something is a function, you can evaluate its address.
Compile this:
printf ("%p\n", printf);Now, try compiling this:
printf ("%p\n", sizeof);[Become a competent programmer faster than you can imagine: pretty-function.org]
