Count-Down Timer in C++

To make a countdown timer we can use the <ctime> library, in C++ to fetch the date and time. Combine it with the std::this_thread::sleep_for() function from <thread> along with chrono::seconds(timePeriod) to have the program pause, for a given period of time.

Approach

• Take the user input for the total number of seconds for the counter.
• Loop until the counter is 0 and print the counter value along with current date and time.
• Make the program wait for one second before the next iteration of the loop. By using std::this_thread::sleep_for(chrono::seconds(1)).
• Keep decrementing the value of counter by one.
• Repeat steps 2-4 until the counter value is less than or equal to zero.

In C++, countdown timers are valuable components in various applications, aiding in scheduling events, controlling timeouts, or displaying the remaining time. In this article, we will learn how to make a countdown timer in C++.

Example:

Input: 
Enter Total Number of Seconds for Countdown Timer: 3

Output: 
Time Remaining: 3
Time Remaining: 2 
Time Remaining: 1 
Time's Up!
