char * test(){return "hello";}char * test2(){    ///Users/lanqs/Desktop/c语言学习/谭启宏-C-9/谭启宏-C-9/main.c:23:12: Address of stack memory associated with local variable 'string' returned//    char string[20] = "HELLO";//    char * string = "HELLO";    char * string = malloc(20);    *string ='b';    *(string +1) ='a';//    free(string);//(有木有这一句后面都没得输出,eee 这一句是对内存的管理不能及时清理,所以应该写在下面)    return string;//直接赋值第二个元素不会输出,因为第一个元素是'\0'}
    //test()    char *temp = test();    printf("temp = %s\n",temp);        //    temp[0]='h';//崩溃//    printf("temp = %s",temp);        temp ="wrold";//指向world地址    printf("temo = %s\n",temp);        //test2()        char *temp1 = test2();    printf("temp1 = %s\n",temp1);

输出结果:

temp = hello

temo = wrold

temp1 = ba


Hello, World!
