Construct an NFA that recognizes language L2 = {x over {1, 0}| x contains both substring 10 and substring 01).

4. Repeat Programming Exercise 3 by declaring numl, num2, and num3, and average of type double. Store 75.35 into numl, -35.56 into num2, and 15.76 into num3.

Suppose that the binary operator + is overloaded as a member function for the . How many parameters does the function operator+ have? (5, 6) Suppose that the binary operator && is overloaded as a nonmember function for the . How many parameters does the function operator&& have? (5,6)

The implementation of a queue in an array, as given in this chapter, uses the variable count to determine whether the queue is empty or full. You can also use the variable count to return the number of elements in the queue. On the other hand, class linkedQueueType does not use such a variable to keep track of the number of elements in the queue. Redefine the class linkedQueueType by adding the variable count to keep track of the number of elements in the queue. Modify the definitions of the functions addQueue and deleteQueue as necessary. Add the function queueCount to return the number of elements in the queue. Also, write a program to test various operations of the class you defined.
