while(printTxt()不通过，要怎么修改

哪抄的?

我自己写的。。正在学类。不断尝试，卡在那了不知道要怎么改。。昨晚连做六小时。。

哦,我以为是之前有个大架子,你七改八改看不懂所以改成现在这个样子呢
原来是自己思路不清晰所以什么都往里面堆,堆成这个样子的

while(printTxt())你这个肯定不行，void txtRead::printTxt()这是个void类型的函数，又没有返回值，怎么能进行while判断呢？你的哦主函数也应该返回一个值，还有chooseSize();函数的调用，要用对象，不能直接写。我给你修改下：
1、bool txtRead::printTxt(){
    while(newsFile.get(news)){
        if(news!=' '&& news!='\n')
        {
            cout<<news;
            return 1;
        }
        else if(news==' ')
        {
            cout<<" ";
            return 0;
        }
        else if(news=='\n'){
            cout<<"\n";
            return 0;
        }
        else if(news=='\0')
        {
            return 0;
            break;
        }
        else return 0;
    }
    newsFile.close();
    return 1;
}
2、chooseSize();这个你得定义个对象，然后调用，我没看懂你的核心，你自己添加吧

话说文件读取还不会呢，哎

看看设计效果图？
