+======Project: library tester======
+A project for C/C++, Data Structures, and System Programming by Karl Krauss for fall 2011.
+Approximately 1 hour for just the tester, then several more for all the libraries.
+=====Objectives=====
+I had spent a lot of time writing various libraries, this program was written as a way to test them all with subtle changes.
+=====Prerequisites=====
+In order to successfully accomplish/perform this project, the listed resources/experiences need to be consulted/achieved:
+  * understand functions
+  * understand pointers
+  * understand structs
+  * understand malloc()
+=====Background=====
+This was the simplest way I could think of to test all of my libraries.
+=====Attributes=====
+====Cprog attributes====
+  * variables
+  * pointers
+  * selection
+  * i/o
+  * repetition
+  * functions
+  * structures
+  * libraries
+====Data Structures====
+  * Pointers
+  * Malloc/new
+  * linked list
+  * Doubly linked list
+  * Libraries
+====Systems programming====
+  * Terminal I/O
+=====Code=====
+This is the code:
+<code c>
+#include <stdio.h>
+#include <stdlib.h>
+#include "queue.h"// this incarnation tested queues/ but can test any of my 3 core libraries
+int main()
+{
+	char selection;
+	int input;
+	Node *tmp;
+	Queue *myQueue;
+	myQueue=(Queue *)malloc(sizeof(Queue));
+	myQueue->start = myQueue->end = tmp = NULL;
+	printf("Press '1' if you wish to create or add to Queue.\n\n");
+	printf("Press '2' if you wish to delete start of a Queue.\n\n");
+	printf("Press '3' if you wish to peek start of Queue\n\n");
+	printf("Press 'q' if you wish to quit: ");
+	scanf("%c", &selection);
+	while (selection != 'q')
+	{
+		if (selection == '1')
+		{
+			printf("What value would you like to store at top of stack: ");//add to top of stack
+			scanf("%d", &input);
+			myQueue = enqueue(myQueue, input);
+		}
+		else if(selection == '2')//delete beginning of queue
+		{
+			tmp = dequeue(myQueue);
+			if (tmp == NULL)
+			{
+				printf("Empty Queue.\n");
+			}
+			else
+			{
+				printf("%d\n", tmp->value);
+			}
+		}
+		else if(selection == '3')//view beginning of queue without deleting
+		{
+			tmp = peek(myQueue);
+			if (tmp == NULL)
+			{
+				printf("Empty queue1.\n");
+			}
+			else
+			{
+				printf("%d\n", tmp->value);
+			}
+		}
+		else
+		{
+			printf("Improper selection please try again.\n\n");
+		}
+		//printf("Press '1' if you wish to create or append a new node.\n\n");
+		//printf("Press '2' if you wish to insert a node.\n\n");
+		//printf("Press '3' if you wish to delete a node\n\n");
+		//printf("press '4' if you wish to print current list\n\n");
+		//printf("Press '-1' if you wish to quit: ");
+		printf("enter a selection: ");
+		getchar();
+		scanf("%c", &selection);
+	}
+	return 0;
+}
