C基础--指针数组

#include <stdio.h>

//指针数组练习
int main1(void)
{
    //int   a[10];
    char*  arry[3] = {"hello", "world", "itcast"};
    //char  arry[3][20] = {"hello", "world", "itcast"};
    //char *str = "hello";
    int i;
    printf("%d\n", sizeof(arry));

    for (i = 0; i < 3; i++)
        printf("%p\t%s\n", arry[i], arry[i]);

    return 0;
}
//指针数组易犯错误
int main(void)
{
    //int   a[10];
    char*  arry[3];            //arry[0] => 0x0
    //char  arry[3][20] = {"hello", "world", "itcast"};
    //char *str = "hello";
    int i;

    for (i = 0; i < 3; i++)
        scanf("%s", arry[i]);        //使用二维数组申请字符串存储空间

    for (i = 0; i < 3; i++)
        printf("%s", arry[i]);

    return 0;
}
