    Question on lesson 10

    Hello,

    Recently, I read the tutorial on C++ File I/O and tried out the source code example given in the tutorial. I used VC++ 6.0.

    The output for the source code is supposed to be ‘ This text will now be inside of example.txt’. However, the output on my pc is only ‘This’.

    It seems that spaces prevent the entire string from being displayed because when I used ‘Thistextwillnowbeinsideofexample.txt’, the whole string is displayed on screen.



    I think the code related to my question is this:



    B_file>>str;

    Cout<<str;



    May I know what went wrong or is the code wrong?



    Please reply….thank you!

    Use fgets, or whatever the crazy C++ equivalent is. B_file>>str; only reads the first word into the string.

    Code:
    char str[512];
    fgets(str, 512, B_File);

    Code:
    #include <string>
    ...
    std::string str;
    getline(file,str,'\n');
