POJ1001 总是RUNTime Error 在我电脑上运行所有测试用例均通过并且没有出现运行时错误
各位请帮忙看一下,真搞不清是什么原因了
使用的gcc版本是4.7 代码如下
代码在我这边运行是没有问题的 代码也仔细检查了很多遍 并且网上关于该题的测试用例也都全部通过了
实在是没检查出为什么会出现Runtime Error的原因
代码如下
#include <stdio.h>
#include <stdlib.h>
#include <string.h>

strcpy(p, p+1);

}

system("pause");

是OJ平台不能通过吗，看看把system("pause");去掉如何
