This document contains code for a clock project. The code takes user input for the hour and minutes and uses trigonometry to calculate the angle of the hour and minute hands based on the input time. It draws the clock face with numbers, and draws the hour and minute hands on the clock using the calculated angles to display the correct time. The code has some comments noting it is for a clock project and intended to display time properly from user input, but that the hands were not working correctly.

//This is clock me made for project.
//Instructed: input time and clock hand is too display time properly.
//Clock hand no work properly
//sorry for bad english.
