无论如何，对于C ++，是否有两次从控制台中的txt文件重定向（cin）输入？

Question

It is rather convenient to redirect input stream from different txt files in CMD console, since I don't need to write a file name and open it in my code. Like typing code.exe < input.txt in windows OS.

However, if I want to redirect two file like input1.txt and input2.txt to two input streams( cin>> ) located in two positions of my code. How should I deal with it? I just know how to redirect once rather than multiple times. Any help would be appreciated.

Answer 1

Getting the two inputs in is the simple problem: TYPE file1.txt file2.txt > code.exe . But how would your first std::cin statement know which line is the last line of file1.txt ?

The normal solution is to use code.exe file1.txt file2.txt , and read both files using their own std::ifstream .
