How do you build a timer in dev c?

To build a timer in Dev-C++, you can use the <chrono> library for time tracking and the <thread> library to pause execution. First, include these headers at the top of your program. Then, use std::chrono::steady_clock to capture the start time and a loop to check the elapsed time, pausing with std::this_thread::sleep_for to create the timer effect. Finally, display the countdown or elapsed time as needed in the console.
