How to generate a random int in C?

Question

Is there a function to generate a random int number in C? Or will I have to use a third party library?

Answer 1

You want to use rand(). Note (VERY IMPORTANT): make sure to set the seed for the rand function. If you do not, your random numbers are not truly random. This is very, very, very important. Thankfully, you can usually use some combination of the system ticks timer and the date to get a good seed.
