    Help getting started with C

    Hi

    I recently installed Turbo C by running install.exe
    It got installed in C:\TC directory.

    I created my first C program and saved it in some other directory C:\ABC

    On Command prompt it I use following statement: tc , it is not recognizing the command. So I did the following:

    edit c:\autoexec.bat

    I added following statement in that:
    set path=%path%;c:\tc\init.bat

    Save & Exit.

    Autoexec (hit enter to execute the file)

    but still I am not able to use commands in directories other than C:\TC

    Any suggestions?

    The PATH environment variable should be a semi-colon delimited list of directories, not files. Find the tc.exe file in that tc directory. Sometimes programs have a bin folder so if you don't find a c:\tc\tc.exe then maybe look for a c:\tc\bin\tc.exe. Whichever directory you find it in, add that directory to your path (i.e. "set path=%path%;c:\tc", or "set path=%path%;c:\tc\bin")

    Or get a compiler that isn't 10 years old Dev-C++ is a very decent one and it's free.

    Thanks for the reply. I downloaded the Dev-C++ and compiled my programs. But after running the program I don't see the output in the results window.

    What could be the possibility?

    Once the program finishes the command window closes. Try adding a getchar() or something to the end of the program so it waits for user input. Or try running your program from inside the command window instead of just double-clicking the icon.

    make sure that u call this sample follwing function before u call the getchar function. provided if you call getchar after the scanf function has called

    Code:
    void clear_buffer(void) // fucntion prototype
    
    void clear_buffer(void)
    {
           int ch;
    
           while((ch=getchar())!='\n' && ch!=EOF);
    }
    to know the reason of why to call this fucntion read the FAQ u will come to know some interesting reason

    Another way ...

    Code:
    #include <stdio.h>
    
    main()
    {
    
        /*
        ...
        ...
        ...
        */
    
        fflush(stdin);
        getchar();
    }

    kosodo,

    It is generally considered irritating when someone asks a question before reading the FAQ.

    Don't use fflush(stdin), ever.

    Sorry, I didn't mean anything but try to help. Those lines of codes are learned from this training cource: http://www.vtc.com/products/cprog.htm. Once again, sorry! I'm reading the FAQ. couldn't imagine it is this helpful ...

    If you see fflush(stdin) in tutorial code (aside from telling you not to use it), then it's a spectacular indication to not trust anything else from it.
