Template alias In c++98/03, we can define an alias for a type by using the TypeDef keyword, such as the typedef unsigned int uint_t, where we have defined unsigned int type aliases and uint_t, We can replace the uint_t with the unsigned int later,

It is undoubtedly a great advantage of object-oriented programming to encapsulate data with functions of processing data, form classes and realize data hiding. But sometimes the encapsulation is not absolute. A friend function provides a mechanism
