    Hi ! I am using C++ to create a new .inf file but problem I am facing that I am not able to enter the 2nd line in new line.

    code is :
    Code:
    #include<iostream.h>
    #include<fstream.h>
    void main()
    {
    ofstream newfile;
    newfile.open("c:\example.inf")
    newfile<<"First Line \n";
    newfile<<"Second Line \n";
    newfile.close()
    }
    output in file is:
    First LineSecond Line

    Kindly rectify me here

    use \r\n instead of \n and see what happens.

    Sir ! I tried this code. but It removes the First character of First Line.
    Source is:
    Code:
    #include<iostream.h>
    #include<conio.h>
    #include<process.h>
    #include<fstream.h>
    void main()
    {
    	char sample[1000];
    	ofstream myfile;
    	myfile.open("c:/example.txt");
    	myfile<<"Writing in the file.";
    	myfile<<"\r \n Next line";
    	cout<<"Done";
    }
    
    Output in file is :
    Code:
    riting in the file.
    Next Line
    
    But I don't understand how did it happen? Like if I tell what i understands from this code.
    I take example of notepad here. Like I opened a text file in notepad. I typed "Writing in the file" then I press HOME key on key board which is I think equivalent to \r(Carriage Return).
    Then I type Next Line. Now the Output would be here as follows :
    Code:
    
    Next LineWriting in the file.
    
    Kindly make me understand.

    Newline is not just \n but its \r\n.

    Thank you Shabbir. It worked.I found my error. Actually i was giving a space between /r and /n which was replacing first character. Thanks Once again.
