c++ - 求大神帮忙解答

Answer 1

An out-of-bounds situation occurred during array access

#include <stdio.h>
#include <string.h>

int main()
{
    void sort(char* []);
    int i;
    char* p[3];
    char str[3][3];
    for (i = 0; i < 3; ++i)
    {
        p[i] = str[i];
    }
    printf("enter number \n");
    for (i = 0; i < 3; ++i)
    {
        scanf("%s", str[i]);
    }
    sort(p);
    for (i = 0; i < 3; ++i)
    {
        printf("%s\n", str[i]);
    }
    return 0;
}

void sort(char* s[])
{
    printf("function called\n");
    int i, j;
    char* t;
    for (i = 0; i < 3; ++i)
    {
        for (j = 0; j < 3 - i; ++j)
        {
            printf("zz\n");
            //当i = 0, j < 3, j = 2时，发生数组越界, j + 1 == 3, 
            //而str[3][3],只有3行。
            if (j < 2 && strcmp(*(s + j), *(s + j + 1)) > 0)
            {
                printf("here\n");
                t = *(s + j);
                printf("%s", t);
                *(s + j) = *(s + j + 1);
                *(s + j + 1) = t;
            }
        }
    }
}
