array::max_size() in C++ STL Last Updated : 30 Jan, 2018 Comments Improve Suggest changes Like Article Like Report Array classes are generally more efficient, light-weight and reliable than C-style arrays. The introduction of array class from C++11 has offered a better alternative for C-style arrays. array::max_size() This function returns the maximum number of elements that the array container can contain. In case of an array, size() and max_size() function always return the same value Syntax : arrayname.max_size() Parameters : No parameter is passed. Returns : It returns the maximum number of elements that the array can contain. Examples: Input : myarray = {1, 2, 3, 4, 5, 6, 7, 8, 9, 0}; myarray.max_size(); Output : 10 Input : myarray = {1, 2, 3, 4, 5}; myarray.max_size(); Output : 5 Errors and Exceptions 1. It throws an error if a parameter is passed. 2. It has a no exception throw guarantee otherwise.
