sleep function in c
The sleep
function in C is used to pause the execution of a program for a specified number of seconds. Here is an explanation of each step involved in using the sleep
function:
Include the necessary header file: To use the
sleep
function, you need to include the<unistd.h>
header file in your program. This header file contains the declaration of thesleep
function.Call the
sleep
function: To pause the execution of your program, you need to call thesleep
function and pass the number of seconds you want to pause as an argument. For example, if you want to pause the program for 5 seconds, you would callsleep(5)
.Program execution pauses: When the
sleep
function is called, the program execution pauses for the specified number of seconds. During this time, the program does not perform any further actions.Program execution resumes: After the specified number of seconds have passed, the program execution resumes from the point immediately after the
sleep
function call.
It is important to note that the sleep
function may not pause the program for an exact number of seconds due to system-specific factors. The actual sleep time may be slightly longer or shorter than the specified time.
Here is an example of using the sleep
function to pause the program for 3 seconds:
#include <unistd.h>
int main() {
// Pause the program for 3 seconds
sleep(3);
// Program execution resumes after 3 seconds
// Continue with the rest of the program
return 0;
}
