Srand(time(0)) executed once at the start of the program, enables a program to generate pseudo-random numbers with variable newseed as the seed.
We evaluate each choice separately to do this.
(a) srand()
The use of srand() in the example above is improper because it needs an argument to be used (2)
(b) srand(time(0))
Because time(0) allows srand() to seed to the current time, the sentence above is acceptable and will always produce unique pseudo random numbers.
(c) Srand (100)
The aforementioned is a legitimate use of srand(), however because srand() has a seed size of only 100, rand() will produce the same set random integers.
(d) time(srand())
