Returns the maximum number of elements that the array container can hold.
The max_size of an array object, just like its size, is always equal to the second template parameter used to instantiate the array template class.
This is a constexpr.
Member type size_type is an alias of the unsigned integral type size_t.
Output:
size and max_size of an array object always match.
No contained elements are accessed: concurrently accessing or modifying them is safe.

std::array::max_size
constexpr size_type max_size() noexcept;
Return maximum size
The max_size of an array object, just like its size, is always equal to the second template parameter used to instantiate the array template class.
Parameters
noneReturn Value
The maximum number of elements the object can hold as content.This is a constexpr.
Member type size_type is an alias of the unsigned integral type size_t.
Example
|
|
Output:
size of myints: 10 max_size of myints: 10 |
size and max_size of an array object always match.
Complexity
Constant.Iterator validity
No changes.Data races
The container is accessed.No contained elements are accessed: concurrently accessing or modifying them is safe.
Exception safety
No-throw guarantee: this member function never throws exceptions.See also

- Return size (public member function)
