C + + language function template Generic programming is a programming method in which the algorithm does not specify the type of data to be operated. Genericity means that the algorithm can be applied to multiple data types as long as it is implemented once. The advantage of generic programming method is to reduce the writing of repeate ...

Implicit type conversion has different conversion methods for different types. Generally, it can be divided into two types, arithmetic type and class type. 1.
