Sequence Constructors Add C++09 Initialization Syntax to Your Homemade Classes
You can initialize C++09 Standard Library containers with a list of initializers, but what about your homemade container classes? Sequence constructors enable you to initialize instances of your homemade classes in a similar fashion.

previous 10-Minute Solution demonstrated the new initialization rules of C++09, which enable you to initialize standard containers (among the rest) in the following manner:
vector <int> scores = {89, 76, 98, 93}; //C++09
A new constructor type called a sequence constructor makes this syntax possible. The following sections will show how to enable the ={val1,val2,...} initialization syntax by adding a sequence constructor to your homemade classes.
