The number of reflexive as well as symmetric relations on a set with 14 distinct elements is __________

The number of reflexive as well as symmetric relations on a set with 14 distinct elements is __________ Correct Answer 291

Let A be a set consists of n distinct elements. There are 2(n*(n-1))/2 number of reflexive and symmetric relations that can be formed. So, here the answer is 214*(14-1)/2 = 291.

Consider the following two C code segment. Y and X are one- and two-dimensional arrays of size n and n × n respectively, where 2 ≤ n ≤ 10.
