Simple Analogue Clock using C/C++

Simple Analogue Clock with C\C++ : The following , is a simple analogue clock , created , using the BGI graphics library of Turbo C/C++ 3.0 :

While running this program , make sure using correct path for the BGI graphics driver .For example : if Turbo C/C++ is installed in the following location "C:\TC" , then the BGI graphics path should be "C:\\TC\\BGI" :
