title: multi dimensional array in cplex c++ concert tech
body: <p>I am trying to create a boolean matrix in c++ concert technology. I have defined 
      <code>typedef IloArray&lt;IloBoolArray&gt; BoolMatrix;</code>
  after that I declared it:    <code>BoolMatrix Assigned(env)</code>;  but while trying input data by    <code>file &gt;&gt; Assigned</code>, it is showing error (no operator ">>" matches these operands). Please help me to come out of this error.
  thanks</p>
