Sleep in c++ linux

In C++, there is the functionality of delay or inactive state which allows the execution to be delayed for a specific period of time. This is often referred to as a “timed delay”. In this article, we will learn how to add timed delay in C++.

Timed Delay in C++

To add a timed delay in C++, we can use the std::this_thread::sleep_for() function from the <thread> library. Pass the duration of the delay as a parameter to the sleep_for() function using chrono::seconds(), which will pause the execution of the program for the specified duration.

Syntax to Use sleep_for Function

this_thread::sleep_for(chrono::duration(time_period));

Here,

• duration can be in various time units like seconds, milliseconds, microseconds, etc.
• time_period is the duration of time for which the current thread is put to sleep.

Note: Due to scheduling and other system factors, the actual sleep time may be longer than the specified time.

The below program demonstrates how we can add timed delay in C++.
