title: Adjacency Matrix and Adjacency List of connected Graph
body: <p>Suppose in a social media network:</p>
  <p>N is friends with K, P, U, X <br/>
  X is friends with N, A, B and C <br/>
  U is friends with A, B and N <br/>
  A is friends with P, U and X <br/>
  B is friends with X and U <br/>
  P is friends with K, N and A <br/>
  K is friends with P, N and M <br/>
  M is friends with C, N and K <br/></p>
  <p>Solve the following problems in c++ <br/>
  a. Write a function to print the adjacency matrix in 2D array and also you have to Draw the
  final graph <br/>
  b. Write a function to print the non connected friends list for everyone. <br/>
  I solved question number (a) as per the requirement of the problem. I am not sure what the question number (b) is asking for.</p>
