What does srand(98) and srand(time (null)) mean?

seeds rand the first srand(98) will result in repeatable numbers from rand each time the program is run. the second supplies the system clock time as a seed value. as a result the numbers generated by rand will be different each time the program is run.

you are welcome. note: the seed is the value in the braces srand(seedValue) if we supply the number 1 as a seed we will get a certain set of results everytime we use rand but they will be different than if we had supplied 98.
