array(C++ 11 新增) 模板类array并非STL容器,因为其长度是固定的。因此不能使用动态调整容器大小的函数如push_back()和insert()等,但是其定义了很有用的成员函数,如operator[]()和at(),正如之前所述,许多标准的STL算法也可用于array对象,如:copy()和for_each()。 操作示例: 1#include <
沒有一個語言如C語言那樣,竟然沒有內建string型別,竟然要靠char array來模擬,不過今天我發現這種方式也是有他的優點。 C語言除了到處用pointer以外,第二個讓我不習慣的就是沒有內建string型別,竟然得用char array來模擬,不過今天發現,因為C語言array跟pointer綁在一起,若用pointer來處理char array,程式其實相當精簡。
In C++, the string can be represented as an array of characters or using string class that is supported by C++. Each string or array element is terminated by a null character. Representing strings using a character array is directly taken from the ‘C’ language as there is no string type...
