Array 是一種大小固定的順序容器。array 的申明：
template <class T, size_t N>class array;
// ‘[]’ 操作#include <iostream>#include <array> int main (){ std::array<int,10> myarray; unsigned int i; // assign some values: for (i=0; i<10; i++) myarray[i] = i * 10; // print content std::cout << "myarray contains:"; for(int &i : myarray) std::cout << " " << i; std::cout << std::endl; return 0;}
// data 成員函數(shù)：返回指向array第一個元素的指針#include <iostream>#include <cstring>#include <array> int main (){ const char* cstr = "Test string"; std::array<char,12> charray; memcpy (charray.data(),cstr,12); std::cout << charray.data() << std::endl; return 0;}
// fill 函數(shù)，設(shè)置array內(nèi)部的所有元素為指定值#include <iostream>#include <array> int main () { std::array<int,6> myarray; myarray.fill(5); std::cout << "myarray contains:"; for ( int& x : myarray) { std::cout << " " << x; } std::cout << std::endl; return 0;}
// swap 函數(shù)：交換兩個array的內(nèi)容，注意兩個array必須是相同類型，相同大小#include <iostream>#include <array> int main (){ std::array<int,5> first = {10, 20, 30, 40, 50}; std::array<int,5> second = {11, 22, 33, 44, 55}; first.swap (second); std::cout << "first:"; for (int& x : first) std::cout << " " << x; std::cout << std::endl; std::cout << "second:"; for (int& x : second) std::cout << " " << x; std::cout << std::endl; return 0;}
