Random number generator

[sudhanshu]

Can anyone plz suggest me an idea to generate pseudo random numbers ?
i tried using time function. can dis be done without using inbuilt functions?

Of course all you have to do is implement a pseudo random number generator algorithm much like the built in functions do.


Lots of information here

Thank you sir for the info.

use this:

time_t seconds = time(NULL); //make sure this is declared at the beginning of the block
srand(seconds);
int a = rand();

If you want to generate the same set of random numbers again and again then seed srand with the same number instead of seconds - ideally pass this as a command line argument or a define at the top of your code.
