variable type cannot be changed after it is declared. s = a; student = s; a = 10.1f ;}
However, in actual development, we often face the following common problems:
1. In a large program, only one or a few places (no more than three places) need to use one or some types (such as Student ), these types are no longer needed elsewhere. Declare a Student type separately. The amount of code required may exceed the amount of code used for this type. The input-output ratio is not cost-effective.
2. In
