An initializer list is used to initialize the data members of a class. This list of members to be initialized is specified in the constructor as a comma-separated list, followed by a colon. Here is an example that demonstrates the use of an initializer list to initialize the variables x and y in the Point class. #include<iostream> using namespace std; class Point { private: int x; int y; public: Point(int i = 0, int j = 0):x(i), y(j) {} /* The above use of the Initializer list is optional as the constructor can also be written as: Point(int i = 0, int j = 0) { x = i; y = j; } */ ...
