这代码里的char*c；c=b; 是什么意思？

Question

```c
#include<stdio.h>
int fun(char* a, char* b)
{
    int n = 0;
    char* c;
    c = b;
    while (*a != '\0')
    {
        if (*a == *b)
        {
            while (*a == *b && *b != '\0')
            {
                a++;
                b++;
            }
        }
        else a++;
        if (*b == '\0')
        {
            n++;
            b = c;
        }
    }
    return n;
}

int main()
{
    char a[100], b[100];
    int n;
    printf("输入：");
    gets_s(a);
    printf("查找：");
    gets_s(b);
    n = fun(a, b);
    printf("结果：%d\n", n);
    return 0;
}

```

Answer 1

char *c;  一个指针
c =b；c指向b所指向的内容，也就是数组b[100];
