    Exclamation How can I read a Hdr file?

    hi everyone.

    I am a newbie in c++. I have an assignment for the university.
    We have to write a program that will read an actual header file from the university's meteosat station and show the date of the file creation and the position of the sat. I was trying to do it with i/o functions but it seems that it is not working.
    Any suggestions how I can read the file?

    Hope to hear anything

    Maz.

    Creation date/time is something you'll get from the OS, check your compilers documentation. What are you using anyway?

    As for reading the file, post some code and a sample of the file contents.
    When all else fails, read the instructions.
    If you're posting code, use code tags: [code] /* insert code here */ [/code]

    What OS do you want the program to run under?

    For Windows OS, consider these Win32 API.

    GetFileAttributes()
    GetFileAttributesEx()

    Question

    Read the header file? Just add this:
    Code:
    #include <your_header_file.h>
    All functions referenced in the header file will then be usable in your .cpp file. Hopefully I'm not misunderstanding what you are asking...

    >>#include

    did you even read the post??

    he's not reading that type of file, just because he said header file. He's reading in a text file containing info on the position of a satellite.

    you need to use file i/o

    Code:
    #include <fstream>
    
    char * satPosition=new char[128]; //make bigger if you need it
    int main()
    {
    ifstream fin("c:\\whatever\\fileCreatedByStation.txt"); //initialize file handle, don't take out the double slashes, they're character escapes
    fin.getline(satPosition,127);
    fin.close();
    
    cout<<satPosition<<endl;
    delete [] satPosition;
    satPosition=NULL;
    return 0;
    }
    PHP and XML
    Let's talk about SAX
