How to design a clock in c++?

How to design a clock in c++ ? write a program that will take quiz related to any topic in given time.

  • Show a clock with the help of graphics library
  • Show the quiz questions related to any topic like C++ language.
  • Take user’s input as the answer of the question.
  • Check whether the answer is correct or not.
  • Matching the answer and print result.
  • Clock stops and quiz ends automatically after certain time.
