为什么这段代码没有输出?
- #include <iostream>
- #include <fstream>
- #include <string>
- int main()
- {
- std::ifstream fin("my.txt");
- if(!fin.is_open())
- std::cout << "open error";
- return 1;
- std::string temp;
- fin >> temp;
- fin.close();
- std::cout << '*' << temp << '*';
- }
复制代码
my.txt
- This is a test file.
- You can write something anywhere.
- It has 70 chars.
- It has 4 lines.

我粘贴了一下,然后代码就变成了这样
- #include <iostream>
- #include <fstream>
- #include <string>
- int main()
- {
- std::ifstream fin("my.txt");
- if(!fin.is_open())
- std::cout << "open error";
- return 1;
- std::string temp;
- fin >> temp;
- fin.close();
- std::cout << '*' << temp << '*';
- }
