How to Delay in C

Method 1 of 2:

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

Method 2 of 2:

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()":
1. #include
Insert, wherever you need your program to make a delay:
1. sleep(1000);
2. 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".
3. 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.
