C++ STL array::empty() function with Example: Here, we are going to learn about a library function empty() of array class, which is used to check whether an array is empty or not.
说明一下,我用的是gcc7.1.0编译器,标准库源代码也是这个版本的。 本篇文章讲述STL中array的使用及原理。 导读 array其实是一个固定大小的数组,元素类型及大小在声明的时候指定,原型如下: template<typename _Tp, std::size_t _Nm> struct array { ... }; 有些书上说array也是一个class,但是我这个版本看到...
C++ STL array::fill() function with Example: Here, we are going to learn about the fill() function of array container in C++ Standard Template Library (STL).
普通数组不支持STL,而当std::vector效率不满足需求的时候array的力量就出来了,使用不是一般的简单。 代码语言:javascript 代码运行次数:0 运行 AI代码解释 std::array<int> arr = {0, 1, 2, 3, 4, 5, 6}; for(std::array<int>::size_type i = 0; i < arr.size(); i ++) std::cout<< ...
print array in C++ Using Iterators Iterators are one of the four pillars of the C++ Standard Template Library, also known as the STL. An iterator points to the memory address of the STL container classes. To some extent, you can relate them with a pointer for better understanding. Iterators...

for_each is a powerful STL algorithm to operate on range elements and apply custom defined functions. It takes range starting and last iterator objects as the first two parameters, and the function object as the third one. In this case, we declare a function object as lambda expression, whic...
