Memset function

#1

In the coding part while assigning all the elements of the array to be 0, why was memset function use. We could simply use the following syntax
pre[1000005]={0}
Does memset function provide any advantage to use?

#2

Yes for 0…both will do the same.
But suppose you want to initialize all locations with 1 or -1… then pre[1000005]={1} will not work. For such case memset can be used. But remember that memset can be use to initialize only with 0,1 or -1.
