+# CS 261 Program 1: Fibonacci
+
+This is my submission for Program 1: Fibonacci for CS 261 - C & Assembly Language Programming, instructed by Dr. Paul Bonamy during the Spring 2024 term at WSU Vancouver.
+
+This work received a score of 50/50 points.
+I don't understand why I wrote it the way I did.
+
+According to the course syllabus, students are allowed to publish their code after the course has ended, so I have done so here.

fib.c

+#include <stdio.h>
+
+int main() {
+  int n = -1;
+  while(n != 0) {
+    // PROMPT USER FOR DESIRED FIBONACCI NUMBER
+    printf("Which fibonacci number?: ");
+    scanf("%d", &n);
+    // IGNORE & REPROMPT FOR NEGATIVE NUMBERS
+    if (n < 0) {continue;}
+    int value;
+    int last1 = 1;
+    int last2 = 0;
+    // Handling special case of 0,1 at beginning of sequence.
+    if (n > 1) {
+      // Adding last two digits in sequence until we reach the desired fibonacci number.
+      for (int c=1; c != n; c++) {
+        value = last1+last2;
+        last2 = last1;
+        last1 = value;
+      }
+    } else {
+      // 0: 0, 1: 1, everything else handled by for loop above.
+      value = n;
+    }
+    // Print result back to user.
+    printf("Fibonacci number %d is %d\n\n", n, value);
+  }
+  return 0;
