array是C++11新增加的一个容器，他可以类似于数组，但比数组安全，array的创建，初始化操作有多种方式，并且还可以使用get进行赋值操作，下面来看下具体的代码：

#include 
   
    #include 
    
     #include 
     
      using namespace std;void createArrayInit(){    //1.创建空array1    array
      
        array1;    cout << "array1.isEmpty = " << array1.empty() << " array1.size = " << array1.size() << " array1.max_size = " << array1.max_size()<< endl;    //2.创建array2有2个元素，值为随机值    array
       
         array2;    cout << "array2.isEmpty = " << array2.empty() << " array2.size = " << array2.size() << " array2.max_size = " << array2.max_size()<< endl;    cout << "array2的值为：" << endl;    for(auto &val: array2)    {        cout << val << "\t";    }    cout << endl;    //3.创建array3有3个元素，分别为23， 56， 18    array
        
          array3 = {23, 56, 18}; cout << "array3.isEmpty = " << array3.empty() << " array3.size = " << array3.size() << " array3.max_size = " << array3.max_size()<< endl; cout << "array3的值为：" << endl; for(auto &val: array3) { cout << val << "\t"; } cout << endl; //4.创建array4,用array3赋值 array
         
           array4 = array3; //array
          
            array4(array3);//这两种方法都可以 cout << "array4.isEmpty = " << array4.empty() << " array4.size = " << array4.size() << " array4.max_size = " << array4.max_size()<< endl; cout << "array4的值为：" << endl; for(auto &val: array4) { cout << val << "\t"; } cout << endl; //5.使用get对array2进行赋值 std::get<0>(array2) = 72; std::get<1>(array2) = 51; cout << "array2的值为：" << std::get<0>(array2) << "\t" << std::get<1>(array2) << endl; //6.创建array5用部分元素初始化为2,其它值为0 array
           
             array5 = {2, 2}; cout << "array5的值为：" << endl; for(auto &val: array5) { cout << val << "\t"; } cout << endl; } int main(){ createArrayInit(); cout << endl; cout << "Hello world" << endl; return 0;}
