C语言编写顺序表的代码

以下是C语言编写顺序表的代码：

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

#define MAXSIZE 100

typedef struct {
    int data[MAXSIZE];
    int length;
} SqList;

void InitList(SqList *L) {
    L->length = 0;
}

int ListInsert(SqList *L, int i, int e) {
    if (i < 1 || i > L->length + 1 || L->length == MAXSIZE) {
        return 0;
    }
    for (int j = L->length; j >= i; j--) {
        L->data[j] = L->data[j - 1];
    }
    L->data[i - 1] = e;
    L->length++;
    return 1;
}

int ListDelete(SqList *L, int i) {
    if (i < 1 || i > L->length) {
        return 0;
    }
    for (int j = i; j < L->length; j++) {
        L->data[j - 1] = L->data[j];
    }
    L->length--;
    return 1;
}

int GetElem(SqList L, int i) {
    if (i < 1 || i > L.length) {
        return -1;
    }
    return L.data[i - 1];
}

int LocateElem(SqList L, int e) {
    for (int i = 0; i < L.length; i++) {
        if (L.data[i] == e) {
            return i + 1;
        }
    }
    return 0;
}

int main() {
    SqList L;
    InitList(&L);
    ListInsert(&L, 1, 1);
    ListInsert(&L, 2, 2);
    ListInsert(&L, 3, 3);
    printf("%d\n", GetElem(L, 2));
    printf("%d\n", LocateElem(L, 3));
    ListDelete(&L, 2);
    printf("%d\n", GetElem(L, 2));
    return 0;
}
