+======Project: More Pointer Fun!!!======
+A project for CSCS 1320 by Paul Sechrist during the Spring 2013.
+=====Objectives=====
+State the purpose of this project. What is the point of this project? What do we hope to accomplish by undertaking it?
+=====Code=====
+<code c 1>
+#include <stdio.h>
+#include <stdlib.h>
+#define NUM_SCORES 5
+#define SCORE0 87
+#define SCORE1 92
+#define SCORE2 97
+#define SCORE3 83
+#define SCORE4 79
+int main()
+{
+        unsigned char *scores;
+        float average;
+        scores = (unsigned char *) malloc (sizeof(unsigned char) * NUM_SCORES);
+        *(scores+0) = SCORE0;
+        *(scores+1) = SCORE1;
+        *(scores+2) = SCORE2;
+        *(scores+3) = SCORE3;
+        *(scores+4) = SCORE4;
+        average = ((float)(SCORE0+SCORE1+SCORE2+SCORE3+SCORE4)/NUM_SCORES);
+        fprintf(stdout, "Your scores are, %hhu, %hhu, %hhu, %hhu, %hhu\n", SCORE0, SCORE1, SCORE2, SCORE3, SCORE4);
