The initializer_list Template (C++11)

Let us understand the concept of initializer_list with the help of an example: #include <iostream>#include <vector>#include <initializer_list>using namespace std;#define MAX 10class array{public: array(std::initializer_list<unsigned int> list) { index = 0; for(auto item: list) { arr[index++] = item; } cout << “C’tor” << endl; } void display() { for (unsigned int i = 0; i < index; ++i) { cout << arr[i] << endl; } }private: unsigned int arr[ MAX]; unsigned short index;};int main(){ array arrObj = {0,1,5,7,8}; arrObj.display(); vector <unsigned int> v = {5,8,9,10,20}; cout << “Entries in vector: ” <<…
