int len = sizeof(namep) / sizeof(char*);
for (int i = 0; i < len-1; i++)

```第一个和第二个交换完 剩下的都是第二的值

char* tmp=NULL;
tmp = namep[j];
namep[j] = namep[j + i];
namep[j + 1] = tmp;
->
char tmp[1000];
strcpy_s(tmp , 1000, namep[j]);
strcpy_s(namep[j] , 1000, namep[j + i]);
strcpy_s(namep[j + 1] , 1000, tmp);
