简单例子分享007：definr和string

鱼蛋代码

#include<stdio.h>
#include<string.h>
#include<stdlib.h>
#define  isay "what a beautiful name."
int main (void)
{
        char name [100];
        printf("please input your name:");
        scanf("%s", name);
        printf("hello %s,%s\n",name ,isay);
        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！
        system("pause");
        return 0;
}
