1. Uniform Initialization

int values[] { 1, 2, 3 };std::vector
     
       v { 2, 3, 5, 7, 11, 13, 17 };std::vector
      
        cities {"Berlin", "New York", "London", "Braunschweig", "Cairo", "Cologne"};std::complex
       
         c{
   4.0,3.0}; // equivalent to c(4.0,3.0)
       
      
     

 

int i; // i has undefined valueint j{}; // j is initialized by 0int* p; // p has undefined valueint* q{}; // q is initialized by nullptr

 

std::initializer_list<>

void print (std::initializer_list
     
       vals){    for (auto p=vals.begin(); p!=vals.end(); ++p) { // process a list of values        std::cout << *p << "\n";    }}// call funcprint ({
   12,3,5,7,11,13,17}); // pass a list of values to print()
