Hi to generate the random number I would still suggest that you use rand() function given by C and use it nicely i.e effectively using seed so that you don�t get same no again and again. I used to use it in my good old collage days. And this function is still being used in most of the software even today
Second method is to divide a second, now whenever you press any key find out which milisecond part of that second take out its unit place and you get a brand new random number. This technique is used in developing an arcade game jackpot las vagas style Third method is to use the system generated datetime stamp multiply the each individual number with each other and take out its unit place of the resultant For some strange reason we have always been using time-space for finding out the unique random number You Last full resort should be Get the no of ticks that your processor gives in a particular duration say 1 sec and get out its last unit digit, obviously your random number generation has to do with your processor speed Thanks bye --- Philip S Tellis <[EMAIL PROTECTED]> wrote: > On Wed, 12 Mar 2003, Manish Jethani wrote: > > > Ok, I get the idea.
