UC知道这么小的程序错在哪里？
来源：百度知道 编辑：UC知道 时间：2024/05/28 10:58:28
#include <iostream.h>
void main()
{
char m_id;
char * b[]={"100001","13213","112465","1324123","2341234","23423","13241","12341234","2341","34234"};
cin>>m_id;
for(int i=0;i<10;i++)
if(m_id==(*(b+i)))
{
cout<<"hehe";
break;
}
if(m_id!=(*(b+i)))
{
cout<<"xixi";
}
}
为什么会有4个错误呢？请高手帮我改改。
但是cout<<*(b+1);可以输出13213啊，所以这种写法应该也没问题吧？问题出在哪里呢？

你把字符、字符串、和字符串数组的概念搞混了
