这段代码是死循环么?

楼主^#

更多发布于：2006-09-20 20:09

#include<stdio.h>
int main()
{
   unsigned char a;
   unsigned short b=500;
   for(a=0;a<b;a++)
   printf("hello\n");
}

The history of these days will be written in blood... By crushing the armies of our enemy, by seizing the weapons they thought to turn against us, we were fighting for our very existence!

是死循环

所谓酷其实就是标新立异,不拘一格,酷是一种植根在内但又表现在外的杂乱无章,是让人心乱如麻心急如焚心花怒放却总是心头一颤的结合;所谓超酷就是这种让人心乱如麻心急如焚心花怒放却总是心头一颤的结合的杂乱无章的酷的一种超脱和升华;超酷就是比酷多一个'超"字以你的智商应该很好区别...

Re:这段代码是死循环么?

同大家看法..关键是char是0~255
如果a到了255之后会怎么样？
