  2. When I running this program I noticed that I have 1 error so this is a message error:
    "fatal ..INCLUDEIOSTREAM.H 19:Error directive: Must use for the type iostream."

    I hope for you to tell how can I fix this problem

    thanks

  3. Microsoft visual c++ gives me this error if i try running it
    '#include ': skipped when looking for precompiled header use
    '#include ': skipped when looking for precompiled header us
    '#include ': skipped when looking for precompiled header use
    '#include ': skipped when looking for precompiled header use

  4. Hei Neeraj Mishra , thank you very much for your effort. I am really enjoying your blog. If it possible can elso write some explanation to your programs for a beginners.

    1. Just copy the whole program and then paste it into notepad. Now save the this file as .cpp extension, for example "demo.cpp".

    give me this error when i running my program
    BGI graphics not supported under window
    how can i fix this problem

    1. Actually BGI graphics works in old compiler like turbo C++. It will not work in modern compilers. Which compiler you are using?

        1. Then the program must work. Just change the path “c:\tc\bgi” with the path of bgi folder of your compiler.

  6. Shubham bansal

    when I running the program only one error is obtain after void main(). that is” declaration syntax error”
    what can I do?

  7. Hello i run it and but here
    ….second hand not working properly ……there is delay of 6 second in 1 shift of 6 degree clock ……what can i do?

  8. Hai sir!
    Can you tell me some books that will help me in c++ coding with line by line explanations.
    Iam a beginner sir.
    Please help me out.

    1. Don’t run it in windows, It is probably Linux or Unix based code. But I believe after certain “tweaks”, the code could be made to run on windows.

  9. NO Offence Mate, but that is the most incompetent and IDIOTIC way to assign a value to a variable upon a certain condition, when there is obviously a pattern in the values of “x”.
    For example in the calculatemin() func, rather than the extensive use of switch-case for every possible value of m, couldn’t you have used simple mathematical expression, viz:
    int calculatemin(int m){
    int x;
    if(m>=15 && m<=60){
    x=360-6*(m-15);
    }
    if(m=0){
    x= 90-6*m;
    }
    return x;
    }
    Seriously Bro! Your code for the rest of the thing quite good, but the function is terribly horrible and quite vexing to even see.
    Regards
    Kudo Shinichi
