Sequentialis tabula linearis repositionis est structura notativa fundamentalis, quae elementa mensae linearis in statuto unitatum repono cum inscriptionibus consecutivis ordine quodam. In hoc diario exsequendam tabulam linearem repositionis sequentiae singillatim accipiemus et tres linguas programmantium C, C# et C ++ ut exempla monstrabimus quomodo tabulam linearem tabulariam sequentem efficiamus.

1. Basic notiones tabularum sequentiarum tabularum linearium

Sequentialis tabula linearis exsequens modum tabulae linearis est exsequenda, quae sequentia habet notas:

Typi elementi idem sunt: ​​elementa in tabula lineari sequential reposita eiusdem generis sunt, et quodlibet elementum certum spatium repono.
Elementa ordinantur: Elementa in indice sequential tabulariorum lineari ordine certo ordinantur, fere in ordine non minuendo.
Temere accessum: Sequentiales tabulae lineares tabulae sequentes confirmant accessum temere, id est, quodlibet elementum in tabula directe accessi potest per indicem.
Expansio dynamica: Sequentiales tabulae lineares repono dynamice dilatare possunt spatium repositionis prout opus est ad plura elementa accommodare.

2. exsequendam sequentem tabulam linearibus repono

1. Data structura definitio

Primum opus est ad structuram datam definire tabularum sequentiarum tabularum linearium. Cum exemplum linguae C accipias, structuram definire potes.

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

typedef struct {
    int *data; // 指向动态分配的数组
    int size;  // 线性表的当前长度
    int capacity; // 线性表的容量
} SequenceList;

2. Initialization

Mensa linearis in serie initialization reponitur et capacitas initialis ei partita est. In C lingua, malloc munus uti possumus ad memoriam dynamice collocandam:

void initSequenceList(SequenceList *list, int capacity) {
    list->data = (int *)malloc(capacity * sizeof(int));
    if (list->data == NULL) {
        exit(-1); // 内存分配失败，退出程序
    }
    list->size = 0;
    list->capacity = capacity;
}

3. addere elementis

Elementa addere ad album successiuum thesaurum linearem. Si capacitas hodierna non sufficit ad nova elementa accommodare, debes primum capacitatem ampliare;

void appendSequenceList(SequenceList *list, int value) {
    if (list->size == list->capacity) {
        // 扩展容量
        int newCapacity = list->capacity * 2;
        int *newData = (int *)malloc(newCapacity * sizeof(int));
        if (newData == NULL) {
            exit(-1); // 内存分配失败，退出程序
        }
        for (int i = 0; i < list->size; i++) {
            newData[i] = list->data[i];
        }
        free(list->data);
        list->data = newData;
        list->capacity = newCapacity;
    }
    list->data[list->size++] = value;
}

4. elementis Access

Accessum determinatum elementorum in indice lineari continue condito:

int getSequenceList(const SequenceList *list, int index) {
    if (index < 0 || index >= list->size) {
        return -1; // 索引无效，返回-1
    }
    return list->data[index];
}

5. Mutare elementa

Determinata elementa in sequentem tabulam linearem mitigare:

void setSequenceList(SequenceList *list, int index, int value) {
    if (index < 0 || index >= list->size) {
        return; // 索引无效，不进行操作
    }
    list->data[index] = value;
}

6. Delere elementis

Delere elementa determinata in serie lineae repositae in album:

void removeSequenceList(SequenceList *list, int index) {
    if (index < 0 || index >= list->size) {
        return; // 索引无效，不进行操作
    }
    for (int i = index + 1; i < list->size; i++) {
        list->data[i - 1] = list->data[i];
    }
    list->size--;
}

7. Solvite

Sequentialem tabulam linearem destrue et in memoriam partita dimitte;

void destroySequenceList(SequenceList *list) {
    free(list->data);
    list->data = NULL;
    list->size = 0;
    list->capacity = 0;
}

3. Exemplum

Infra tres programmantes linguas C, C# et C++ utimur, ad tabulam linearem sequentem repositionis deducendam, ac elementa in tabula lineari addendo, deleo, accessu et imprimendo.
