从用户(L1 和 L2)读取两个数组并在 L2 是 L1 的子数组时打印 L1 - L2 的程序

Program that read two arrays from the user(L1 and L2) and prints L1 - L2 if L2 is a sub array of L1

我创建了这个程序,它从用户(L1 和 L2)读取两个数组,如果 L2 是 L1.For 示例的子数组,则打印 L1 - L2,如果 L1 ={'a', '2','c','d','e'} 和 L2 ={'2','c','d'} 然后 它应该打印 {'a', 'e'}。但是我在输出中遇到了一些问题。我只得到一些值的正确输出,但对于大多数值,我得到的 L2 不是 L1 的子数组。

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

int main() {
    int n1, n2, j = 0, i = 0, temp = 0, a = 0;

    //ARRAY INPUT
    printf("Enter number of characters in L1: ");
    scanf("%d", &n1);
    int l1[n1];
    for (int i = 0; i < n1; i++) {
        printf("Enter character %d: ", i + 1); 
        scanf(" %c", &l1[i]);
    }
    printf("Enter number of characters in L2: ");
    scanf("%d", &n2);
    int l2[n2];
    for (int i = 0; i < n2; i++) {
        printf("Enter character %d: ",i + 1); 
        scanf(" %c", &l2[i]);
    }
    
    //FOR L1 > L2
    while (i < n1) {
        if(l1[i] == l2[j]) {
            i++;
            j++;
            if (j == n2) {
                a = 1; 
                break;
            }
        }
        else {
            i = temp + 1;
            temp = i;
            j = 0;
        }
    }
    
    if (a == 0) {
        printf("l2 is not a sub array of l1");
    }
    else if (a == 1) {
        printf("{");
        for (int i = 0; i < n1; i++) {
            if (i >= temp && i < (temp + n2)) 
                continue;
            printf("%c ", l1[i]);
        }
        printf("}");
    }

    exit(0);
}```

您的 'Arrays' 应该是 char 数组而不是 int

char l1[n1];
char l2[n2];
