What does the following declaration means?

Question

I'm new to programming world and i'm studying about pointers and array. and i read this code on a website. what does this line of mean?

 int(*ptr)[10];

Is it a pointer or an array of size 10?

Both. It's a pointer to an array of size 10. And conversely `int* ptr[10]` would be an array (of size 10) of pointers. — john, Mar 23 '19 at 10:04
Removed the C++ tag since no-one in their right mind would use this :-) Also closed as dupe since there is a perfectly good canonical question on how to read C types. — paxdiablo, Mar 23 '19 at 10:14

It is a pointer to an array of 10 int.

Instead int *ptr[10] is an array of 10 int pointers.

Therefore it's a pointer to an array.

For another example, in int main(int argc, char* argv[]), argv is an array of pointers.
