区分英文和中文的问题

[kivien]

下面代码想只把英文找出来，但是它把中文也找出来了【当然也过滤了一些中文】……

        CString &originaltext;//这是引用传递进来的

	if(""==originaltext)
		return;
	setlocale( LC_ALL, "" );//解决问题：_ASSERTE((unsigned)(c + 1) <= 256);程序中断
	int len=originaltext.GetLength(),i=0;
	for(i=0;i<len;i++){
		if(isalpha(originaltext[i])==0)//当前不是字母，即不为a-z,A-Z
		{
			if((originaltext[i]=='-'||originaltext[i]=='\''))   //it's  that's  co-worker
			{
				if((i-1>0&&isalpha(originaltext[i-1]))&&(i+1<len&&isalpha(originaltext[i+1])))
					end++;
			}
			else{
				if(end!=-1)  //end of word
				{
					word=originaltext.Mid(begin,end-begin+1);//word
					word.MakeLower();
					Insert_Pair=mapText.insert(pair<CString,stu>(word,stuTmp));//mapText存储单词
					if(Insert_Pair.second==false){
						miter=mapText.find(word);
						if(miter!=mapText.end()){
							miter->second.count++;
						}
					}
					end=-1;
				}
			}
		}else{							//当前为字母
			if(end==-1){   //如果是第一个字母
				begin=i;
				end=i;
			}else			//如果不是第一个字母
				end++;
		}
	}

一直在等一个人回复。 因为无满意结贴不返回分数，嘿嘿。

	for(i=0;i<len;i++){
		if(originaltext[i]<255&&originaltext[i]>0){//扩充的ASCII字符范围为0-255,如是,处理一个字节
//处理英文
		}else{//<0,>255的是汉字,处理两个字节
//处理中文等文体的文字
			i++;
		}
	}

同一个人不能连续回复3次？

使用iswalpha或 _ismbcalpha
