write program in c++or c

sri my questuon is that
write a program in corc++
to check wether a relation is equlance or not using two dimensional array

What is 'equlance'? Please proofread your question before you dump your

It is "equivalenc e" but it doesn't help much - relation between what and what is must know.

Ah, ok, that is easy then: for a binary relation R(x, y) check whether or not for
any a and b:

1) R(a, a)
2) if R(a,b) then R(b,a)
3) if R(a,b) and R(b,c) then R(a,c)

The OP should be able to loop over his/her matrix and check the above criteria.

kind regards,

sir ur answer explained the logic of the programme,
but yet i do not understand how check the equalence within the programming language
plz give some hints or if possible write the programme

[ASIM ABBAS]

the term equalence is from discrete mathematics
its defined as that a set is said to b equlence if it is transitive,refl exive and symmetric at the same time

The term is 'equivalence'.

Write a boolean function R:

bool R(T a, T b) { ... }

... such that it returns true if the relation R(a, b) holds, false otherwise. Check
your entire matrix using this boolean function, e.g.

1) all elements on the diagonal R(a,a) should be true
2) for all other elements R(a,b) == R(b,a)
3) left as an exercise to the reader.

kind regards,
