简单例子分享007：definr和string

鱼蛋代码

1. #include<stdio.h>
   
2. #include<string.h>
   
3. #include<stdlib.h>
   
4. #define  isay "what a beautiful name."
   
5. int main (void)
   
6. {
   
7.         char name [100];
   
8.         printf("please input your name:");
   
9.         scanf("%s", name);
   
10.         printf("hello %s,%s\n",name ,isay);
    
11.         printf("your name of %lu letter,must have %lu\n ", strlen (name) ,sizeof name);//vs2012无法识别%zd,可以用%u或%ul代替！
    
12.         system("pause");
    
13.         return 0;
    
14. }
