编写功能菜单程序，实现初始化、线性表遍历、插入、删除4个基本操作

好的，以下是一个简单的功能菜单程序，实现了初始化、线性表遍历、插入、删除4个基本操作：

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

#define MAXSIZE 100

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

void initList(List *L) {
    L->length = 0;
}

void traverseList(List L) {
    int i;
    for (i = 0; i < L.length; i++) {
        printf("%d ", L.data[i]);
    }
    printf("\n");
}

int insertList(List *L, int pos, int value) {
    int i;
    if (pos < 1 || pos > L->length + 1 || L->length == MAXSIZE) {
        return 0;
    }
    for (i = L->length - 1; i >= pos - 1; i--) {
        L->data[i + 1] = L->data[i];
    }
    L->data[pos - 1] = value;
    L->length++;
    return 1;
}

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

int main() {
    List L;
    int choice, pos, value;
    initList(&L);
    while (1) {
        printf("1. Traverse list\n");
        printf("2. Insert element\n");
        printf("3. Delete element\n");
        printf("4. Exit\n");
        printf("Enter your choice: ");
        scanf("%d", &choice);
        switch (choice) {
            case 1:
                traverseList(L);
                break;
            case 2:
                printf("Enter position and value: ");
                scanf("%d %d", &pos, &value);
                if (insertList(&L, pos, value)) {
                    printf("Insert successful\n");
                } else {
                    printf("Insert failed\n");
                }
                break;
            case 3:
                printf("Enter position: ");
                scanf("%d", &pos);
                if (deleteList(&L, pos)) {
                    printf("Delete successful\n");
                } else {
                    printf("Delete failed\n");
                }
                break;
            case 4:
                exit(0);
            default:
                printf("Invalid choice\n");
        }
    }
    return 0;
}

希望这个程序能够帮到你！
