The c_str() method represents the sequence of characters in an array of string followed by a null character (‘\0’). It returns a null pointer to the string. Syntax: string-name.c_str(); Copy At first, we use c_str() method to get all the characters of the string along with...
std::array 教程(来自cppreference.com) std::array - C++容器库 在头文件中定义 模板: template<class T,std::size_t N> struct array; 自C++11开始有的。 简介 std::array是一个封装固定大小数组的容器。 这种容器型别其语义与只含有一笔以T[N]表示之C风格阵列做为它唯一非静态数据成员之struct相同。
array anywhere a pointer is expected, and vice versa. A function can handle arrays, but define the type it recieves as a pointer. And since arrays are pointers (constant pointers), they are passed call by reference, meaning the array passed will be modified immediately in the calling ...
