我需要你对错误的看法.
在家里,我用Bloodsheed编写了一个程序并得到了想要的结果.该程序的目的是显示源文件中的行以输出具有特定宽度的文本.源文件无法逐行分析.相反,它应该使用char和string word来读取.
然后我去了uni使用TextPad和Borland提交我的程序:输出是不同的:单词之间的空格和一些行尾字符被忽略.我不明白发生了什么.我花了整整一天的时间没有成功.编译器使用不同的运算符>>来读取字符串吗？看起来在第一种情况下,它在第二种情况下在空格或行尾字符之前停止它丢弃它们.你有关于这个问题的建议吗？
在家里成功的输出是:
Max line length: 40

}
