关于结构体数组中指针的小困惑
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
typedef struct test{
int a;
int b;
char *c;
}TEST;
int main()
{
TEST ts[2];
TEST *ptr = (TEST *)malloc(sizeof(TEST));
TEST un;
un.c = (char *)malloc(10);
ptr->c = (char *)malloc(10);
ts[0].c = (char *)malloc(10);
ts[1].c = (char *)malloc(10);
memset(ts, 0x0, sizeof(TEST)*2);
ts[0].a = 1;
ts[1].b = 1;
strcpy(&ts[0].c, "abc");//这点为什么是&ts[0].c而不是ts[0].c？
printf("ts[0].c = 0x%x &ts[0].c = 0x%x \n",ts[0].c, &ts[0].c);
ts[1].a = 2;
ts[1].b = 2;
strcpy(&ts[1].c, "def");
printf("ts[1].a b c = %d %d %s \n", ts[1].a, ts[1].b, &ts[1].c);
ptr->a = 3;
ptr->b = 3;
strcpy(ptr->c, "hij");
printf("ptr->a b c = %d %d %s \n",ptr->a, ptr->b, ptr->c);
printf("ptr->c = 0x%x \n", ptr->c);
un.a = 4;
un.b = 4;
strcpy(un.c, "klm");
printf("un.a b c = %d %d %s \n",un.a, un.b, un.c);
return 0;
}
