    Question about file I/O

    Im curious, if i want to find a file on my c: say its a txt file named hello.txt. Is there any special syntax that is involved with doing so through c++? I mean can i just say open file so and so and than just do my programming after that or do i need anything else to go with it?

    you didn't quite specify your question enough, either you are asking to have an algorithm to "search" for a file on your hard drive, or open a file from your c: drive???????


    if you want to open a file, you would have to make up your mind and decide if you want to designate this file for reading from it or writing to it....


    [CODE]

    #include <fstream.h> // you need to include this header file

    ifstream fin("c:\\TextFile.txt"); // opens a file for reading

    ..................................................


    ofstream fout("c:\\OtherTextFile.txt"); // opens a file for writing






    Hope this helps....

    Im sorry. Id like to know, how i can go about having the user enter a file and than having c search the computer(and or drives) to find it. Either that or im looking to find some tutorials that can help me with this. Id rather try to struggle with it than just have it given, kinda make me feel like i did it on my own.

    to tell you the truth i don't remember of the top of my head what the template function you might use to search the c: drive...

    however, i am very sure that you can make a binary search algorith (home made one).......what you simply would do is compare file by file in the whole hard drive until you find the desired one.....

    if you want i will look around, if i will find something then i will let you know........

    unless someone else can answer this question first........
