Assuming we have to find prime numbers between 1 to 100, each number (let us say x) in the range needs to be successively checked for divisibility by 2 to x-1. Then you pass the seed value to the "srandom()" function. In Java programming, we often required to generate random numbers while we develop applications. Why is the air inside an igloo warmer than its outside? Is Harry Potter the only student with glasses?
