Analog Clock source code using c++ and winBGI graphics

This code does not run directly in code::blocks because winBGIm graphics is for turbo compiler where you can run this code directly and we don’t have to setup library but in code::block you have to setup.To setup WinBGIm graphics library you can see my previous post here .If you setup then now you are ready to compile this code.
Copy the code below and compile it in code::block.While compiling if you got error message in line 320 of graphics.h :” redefination of int right” then change int right=0 to int top = 0.Although,you got other error then leave the message.



I hope this code may help and  seems  interesting for you.

  1. "ANALOG_CLOCK.exe has stopped working"
    what should i do now?

    1. run under a debugger, then when stops examine the stack trace and current variable values. One possibility is some/any keyboard button was pressed, which will cause the program to exit.

    2. The problem is the faulty libbgi.a file.
      Download the file from
      https://github.com/stahta01/windows-games/blob/master/WinBGIm/lib/libbgi.a
      Works perfectly!!

    1. usually need admin privileges to open files in d:\Program Files...\ suggest running code blocks as administrator or producing file elsewhere then logon as administrator to copy the executable to the target location. BTW: does the ...\CodeBlocks\ directory exist?

    2. change your file extension to *.c from *.cpp

  5. change your *.c extension by *.cpp...
