C-Language Data Structure: Use a flag to implement a cyclic queue and a data structure queue 1 # include Although it is implemented with a flag, an error occurs when you replace the int type array with a char type array. In this case, we will keep you in doubt and wait for you to solve the problem.

Data Type The C language provides a wide range of data types, which can be divided into two categories: Basic Types and constructed data types.The primary feature of basic data types is that they cannot be further decomposed into other types. That is to say, the basic
