Detailed explanation of the examples of C language implementing static order tables
Linear Table
Defining a sequential table means opening up a continuous storage space in memory and identifying it with a name. Only when a sequence table is defined can the order table be used to store data elements and can various operations be performed on the order table.
Next, take a look at the static order table and directly follow the code:
