Assume that a bool variable isQuadrilateral has been declared, and that an int variable, numberOfSides has been declared and initialized. Write a statement that assigns the value of isQuadrilateral to true if numberOfSides is exactly 4 and false otherwise.

Instructor Notes:
Hint: The result of evaluating a conditional expression is true/false, and can be assigned to bool variable, e.g.,
bool x = y == z;
Note == is the relational equality operator and = is the assignment operator. This statement will compare y and z to see if they are equal, which is either true or false. Then the true/false value will be assigned to Boolean variable x.
