How to Delay in C

Steps

Make your CPU work for some time without producing any noticeable event.

Do no other operation during that delay, in order to create a simple time-delay.

The "for-loop" technique

Use a typical "for" loop followed by a null statement to implement time delay.

Write as follows, for an example: for (i=1 ; i<100 ; i++) ; The statement followed by the ";" makes the computer execute the loop 100 times without any noticeable event. It just creates a time delay.

The "sleep()" Technique

Use sleep() The function called sleep(int ms) declared in which makes the program wait for the time in milliseconds specified.

Include the following line in your program before "int main()": #include

Insert, wherever you need your program to make a delay: sleep(1000); Change the "1000" to the number of milliseconds you want to wait (for example, if you want to make a 2 second delay, replace it with "2000". Tip: On some systems the value might refer to seconds, instead of milliseconds. So sometimes 1000 isn't one second, but, in fact, 1000 seconds.
