C Queue Operations: Enqueue, Dequeue, and Print

The code creates a queue data structure and performs various operations on it.

First, the queue is initialized using the function 'Init Queue(Q)'.

Then, the characters 'h', 'r', and 'y' are added to the queue using the function 'EnQueue(Q, character)'.

Next, the character at the front of the queue is removed and stored in the variable 'x' using the function 'DeQueue(Q, x)'.

The character 'x' is then added back to the queue using the function 'EnQueue(Q, x)'.

The character at the front of the queue is again removed and stored in 'x'.

The character 'a' is added to the queue using 'EnQueue(Q, 'a')'.

Finally, the while loop removes each character from the queue and prints it using 'DeQueue(Q, y)' and 'printf(y)', respectively. After the while loop, the value of 'x' is printed using 'printf(x)'.

The output of this code will be the characters 'h', 'r', 'y', 'e', 'c', and 'a', followed by the value of 'x' (which will depend on its initial value, since it is not explicitly set in the code).
