Create a delay in time in a C program The key point to note here is that this delay function accepts parameter in milliseconds. That is if we want to create a 1-second delay in our program we have to pass 1000 as a parameter to the function. Example of delay in C. The sleepfor function makes the thread it is invoked on (here, the one associated with the std::thread we’re building) wait for at least the indicated delay. In practice it could be a little longer if the OS is not ready to hand back the execution to the thread.

Neon-Vibe wrote I was wondering if anybody new a command that can be used in c to add a time delay between when commands are carried out. Preferably the duration of the delay can be set by the programmer. The above example will use up CPU processes while waiting. Here unsigned int is the number of milliseconds (remember 1 second = 1000 milliseconds). To use delay function in your program you should include the 'dos.h' header file which is not a part of standard C library. Delay in C program If you don't wish to use delay function then you can use loops to produce delay in a C program.

To start calculating time in C with Windows high-resolution time stamps in native user-mode C code, there are a couple of Windows APIs you’ll want to note. The first is QueryPerformanceCounter. This function retrieves the current value of the performance counter. This C Sleep tutorial will discuss the Sleep Function in C & see how to put a thread to sleep. We will also learn about the other functions viz. Usleep: Any computer program that is a process, task or thread may ‘sleep’ or go into an inactive state for a specific time. The execution is suspended, for this period of time.

Hello everyone, In this post, we will learn about the delay() function in C++. There can be many instances when we need to create a delay in our programs. C++ provides us with an easy way to do so. We can use a delay() function for this purpose in our code. This function is imported from the “dos.h” header file in C++. We can run the code after a specific time in C++ using delay() function.

delay() function in C++

Now let us understand the syntax for delay() function. It is as follows:

void delay(unsigned int milliseconds);

Explanation:

Here, void suggests that this function returns nothing.
‘delay’ is the function name.
The function takes one parameter which is unsigned integer.

The key point to note here is that this delay() function accepts parameter in milliseconds. That is if we want to create a 1-second delay in our program we have to pass 1000 as a parameter to the function.

Example of delay() in C++

OUTPUT:

How it worked:

As you can see in the program, we are taking input from the user ( To know: Taking only integer input in C++ ) and passing it to the delay function after multiplying it with 1000 to convert the seconds into milliseconds.
“dos.h” header file has been included so that a call to delay() function can be made.
