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

Answer 1

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.

Answer 2

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.

Answer 3

thank you

Answer 4

Ok, but what if we gave it some other number ?
