In C# , timers are easily created and managed using specific built-in classes, but C+ + requires a different approach. This guide will guide you through creating your own periodic timer using C+ + threads and functions, ensuring you can achieve the same behavior as in C# . The Challenge In C# , you can define a timer like so: [[See Video to Reveal this Text or Code Snippet]] In this example, a timer is initialized to tick every 5 milliseconds, triggering an event handler function. Your task is to achieve similar functionality in C+ + . Let's explore how you can implement this. Implementing a Periodic Timer in C+ + Step 1: Basic Timer Class You can create a custom class that utilizes a thread to call a function at defined time intervals. Below is a simple implementation that you can tweak as necessary: [[See Video to Reveal this Text or Code Snippet]] Step 2: Using Your Timer Class Now let's create a simple demonstration of how you can use this timer class in the main function: [[See Video to Reveal this Text or Code Snippet]] When you run this program, it will output "Tick" every 5 seconds, demonstrating the periodic timer functionality. Step 3: Enhancing Responsiveness with Condition Variables To make your timer class more responsive, you can implement a condition_variable. This allows you to interrupt the sleep state and handle shutdowns more gracefully: [[See Video to Reveal this Text or Code Snippet]] This implementation allows for timely shutdowns, ensuring that if you call the destructor, the timer will stop promptly rather than waiting for the next tick. Conclusion By utilizing threading and condition variables in C+ + , you can successfully create a timer that calls a function at periodic intervals, akin to the behavior seen in C# . This approach empowers you to incorporate timed operations into your C+ + applications, providing flexibility and responsiveness.
