Write a C program that will take 3 positive integers as input and verify whether they form a Pythagorean triplet or not.

A Pythagorean triplet consists of three positive integers X, Y, and Z, such that 
X2 + Y2 = Z2. A right angled triangle whose sides are Pythagorean triplet is called a Pythagorean triangle. For example : 3, 4 and 5 are pythagorean triplet(32 + 42 = 52).
