如果用一个字符串字面常量来初始化一个字符数组,数组的长度至少要比字符串长度大1,因为还要保存/0.如char array[] = “Hello”;数组的元素其实是{‘H’,’e’,’l’,’l’,’o’,’’/0}。 4,引用和指针 A, 引用在创建的同时必须初始化,而指针在定义的时候不必初始化,可以在定义后面的任何地方重新赋值。

The C++ STL min_element, max_element and minmax_element (C++ 11) are useful functions from header algorithms to get the min, max, and min-and-max iterator from a given range of iterators. These functions take first parameter the begin iterator of a range (vector, list or array), and ...
Was it ever proposed? There are probably many STL functions that don't work with pointers. If you had two pointers to element of the same array youcoulduse std::min to get the one with the smaller index so it already has a meaning. It's probably not used like this very often, so ...
When we have the min/max value from each vector, we should apply std::ranges::max/std::ranges::min to that set of values, rather than hand-crafting the greatest-of three. Talking of ranges, the views library allows us create a concatenation of all three arrays and ...
