Wait for seconds using sleep_for() function in C++ Let us see how we can use these functions to wait for a given number of seconds in C++. For this purpose, there are two functions defined in C++ namely sleep_for() function and sleep_until() function.

As we know that threads are lighter processes running within a process, you can use threads to make the program wait for a few seconds in C++. This will help you understand the working of the sleep() function in C++.īeginning with C++11, we are provided with two functions to wait for seconds using threads in C++.

You can copy this code and run it on your machine by giving different values as input to the sleep() function. Upon execution of the sleep() function, the program waits for 5 seconds before reaching the second output line.

After that, the sleep() function is executed which is given 5 as its input argument.

In the above program, after including the necessary libraries, we output to the console the first line.Now, let us write a simple c++ program to demonstrate how the sleep() function can be used to wait for seconds in C++. However, due to some priority issues and scheduling by the operating system, the actual wait time may be longer than the number of seconds passed as input. The program resumes its execution after the time is over or if an interrupt occurs in between. The sleep() function causes the program to go to a sleep state for the number of seconds that we pass to the function as input argument. total number of seconds we wanted the program to wait minus the total number of seconds the sleep() function has executed. However, if the program is interrupted in between the execution of the sleep() function, it returns the number of seconds left i.e. It returns 0 if the sleep function completes its execution and the program has waited for the number of seconds you specified. The sleep() function also has a return value. The sleep() function accepts an unsigned integer denoting the number of seconds you want your program to wait. However, we can use the sleep function provided by operating systems that we are working on in our own program. Wait For Seconds Using The sleep () Function in C++Ĭ++ does not provide us with any sleep function of its own. Let us discuss them one by one, using examples and code so that we can understand how each function can be used to wait for the desired number of seconds in C++. We will discuss sleep, delay, wait, and timer in C++. In this article, we will discuss all the available functionalities and libraries in c++ that can be used to add the delay or wait for seconds in our C++ program. For instance, if we are waiting for a job to finish, we want to put something on hold, or we need something to be done periodically, we often need functionalities that can enable us to add timed delays to our program. For this, C++ provides us with very useful resources to add timed delay, sleep, etc into our program. There are multiple instances when we need to add delay to our program.
