读取输入文件时空格不打印 [英] spaces are not printing when reads the input file

问题描述

我试图读取输入文件的每个'char'，并写入输出文件，直到找到'？'作为文件的结尾。每个字符都写在输出文件中，除了单词之间的空格。我不知道这是什么错误代码？

I am trying to read each 'char' of the input file and write in the output file until finds the '?' as the end of file . Every char is written in output file except the spaces between words. I dont know what's wrong in this code??

#include <iostream>
#include <fstream>
using namespace std;
int main()
{
   ifstream infile("in.txt");
   ofstream outfile("out.txt");
   char ch;
   infile >> ch;
   while(ch != '?')
   {
     outfile<<ch;
     infile >> ch;
   }
}

推荐答案

在阅读时使用 noskipws ...

Try using noskipws on read...

infile >> noskipws >> ch;

noskipws告诉输入流不跳过默认情况下执行的空格。

The noskipws tells the input stream to not skip whitespace which it does by default.
