Implementation of simple reading and writing of text files in C ++

The Code is as follows: Copy codeThe Code is as follows: # include "stdafx. h"
# Include <iostream>
# Include <fstream>
Using namespace std;
Int _ tmain (int argc, _ TCHAR * argv [])
{
// Write a file
Ofstream ofs; // provides the file Writing Function
Ofs. open ("d: \ com.txt", ios: trunc); // trunc clears the existing file stream when opening the file. If the file does not exist, create
Int I;
Char a = 'a ';
For (I = 1; I! = 27; ++ I)
{
If (I <10)
{
Ofs <"0" <I <"\ t" <a <"\ n ";
A ++;
}
Else
{
Ofs <I <"\ t" <a <"\ n ";
A ++;
}
}
Ofs. close ();
// Read the file to the console
Char buffer [256];
Ifstream ifs; // provides the File Reading Function
Ifs. open ("d: \ com.txt", ios: in); // in -- open the file for read Operations
The content in cout <"d :\\ com.txt" <"is as follows:" <endl;
While (! Ifs. eof () // determines whether the stream ends.
{
Ifs. getline (buffer, 256, '\ n'); // The number of characters reaches 256 or ends when a line break occurs.
Cout <buffer <endl;
}
Ifs. close ();
}
