The C language implements an example of a static sequence table

The linear table

To define a sequence table is to carve out a contiguous segment of memory and identify it with a name. Only when a sequence table is defined can data elements be stored in the sequence table and various operations be performed on the sequence table.

Next, take a look at the static sequence table and go directly to the code:

SeqList.h

#include <stdio.h>
#include <stdlib.h>
#include <assert.h>
#include <string.h>

#define MAX 10

typedef int DataType;

typedef struct SeqList
{
 DataType data[MAX];
 int sz;
}SeqList,*pSeqList;

void InitSeqList(pSeqList ps);
void PushBack(pSeqList ps, DataType d);
void PopBack(pSeqList ps);
void PushFront(pSeqList ps, DataType d);
void PopFront(pSeqList ps);
void Display(const pSeqList ps);
int Find(pSeqList ps, DataType d);
void Insert(pSeqList ps, DataType d, int pos);
void Remove(pSeqList ps, DataType d);
void RemoveAll(pSeqList ps, DataType d);
void Reverse(pSeqList ps);
void Sort(pSeqList ps);
