Initialization of the C++11

C++11 type initial more convenient such as

??

Vector<int> VEC = {A-i};

Vector<int> vec{1,2,3};

Map<string, int> m = {{"Help", 3}, {"Good", 4}};

??

Other common examples include how a class that you define accepts list initialization

struct class supports simpler initialization in C++11 without the use of handwritten initialization functions

Class Node

{

Public

int x;

Double y;

String Z;

};

??

Class Vec

{

Public

VEC (const initializer_list<double>& IL)

:d ATA (IL)

{

??

}

Vector<double> data;

};

??

??

TEST (Simple, func)

{

Node node{1, 3.5, "Meixi"};

Pval3 (node.x, Node.y, node.z);

??

Vec vec{1.2, 3.4, 5.6};

Pvec (Vec.data);

}
