C++11新特性——大括号初始化

//小括号初始化
string str("hello");

//等号初始化
string str="hello";

//大括号初始化
struct Studnet{
    char* name;
    int age;
};
Studnet s={"dablelv",18}; //纯数据（Plain of Data,POD）类型对象
Studnet sArr[]={{"dablelv",18},{"tommy",19}};  //POD数组

class Test{    
    int a;    
    int b;    
public:    
    C(int i, int j);    
};    
Test t{0,0};                    //C++11 only，相当于 Test t(0,0);    
Test* pT=new Test{1,2};         //C++11 only，相当于 Test* pT=new Test{1,2};    
int* a = new int[3]{ 1, 2, 0 }; //C++11 only

// C++11 container initializer
