Stopwatch:
This is a source code for stopwatch in C++. In this we have used a class named tym as shown in the source code given below. In this class we have used four private elements one for hour , second for minute , third for second and fourth for less than a second. There are some member functions used in this class for the initialisation and to store the values of time. The source code for the same is given below you can check it out.
