C language to implement the dynamic sequence table implementation code
A sequence table is a linear table stored as an array in computer memory. It is a linear structure in which data elements are stored in sequence in a set of contiguous storage locations. A linear table is called a sequential table if it is stored sequentially. A sequential table is one in which the nodes of a table are sequentially stored in a set of contiguous locations in the computer's memory.
Static implementation: only two members are needed inside the structure, one of which is a fixed-size (MAX) array to hold our data. The array size can be changed by changing the value of MAX in the header file.
Dynamic implementation: in memory to open up a block of space, with the increase in the number of our data to expand capacity.
Take a look at the dynamic order table implementation:
