指针传递参数，有点不理解了
测试一下形参，但是有了新的疑惑。主函数输出的乱码，和out函数输出竟然不一致，我明明传指针进去的啊
程序代码：#include<stdio.h>
#include<string.h>
char *Get1()
{
char a[8];
scanf("%s", a);
printf("Get :%s\n", a);
return a;
}
char *Get2()
{
char a[] = "dfhbdh";
printf("Get :%s\n", a);
return a;
}
char *Get3()
{
char *a = "dfhbdh";
printf("Get :%s\n", a);
return a;
}
void Out(char *a)
{
printf("Out :%s\n\n", a);
}
int main()
{
char *s1 = Get1();
printf("Main:%s\n", s1);
Out(s1);
char *s2 = Get2();
printf("Main:%s\n", s2);
Out(s2);
char *s3 = Get2();
printf("Main:%s\n", s3);
Out(s3);
return 0;
}
