- I've yet to encounter a programmable device that…didn't have some sort of internal clock.…Computer has a clock and thanks to the Internet…modern computers keep accurate track of the time.…When your code needs to access that information…you dip into the C language library's…assortment of time functions.…In this movie you'll see how time…functions work in the C language.…You'll learn how to check the time, read time values,…and how to gather information about the current date.…
This code uses the direct value…generated by the time function, as shown by the…second argument in the printf function at line six.…You'll see that the placeholder is ld,…which is a long integer value or a very large integer.…That's the type of value returned from the time function.…The time function itself requires an argument.…Here I'm using the NULL pointer…constant to keep the function happy.…
Also keeping the compiler happy is the inclusion…of the time header file at line two.…Build and run this code.…So this value is the current time.…
