+       Exercise 1-6. Verify that the expression getchar() != EOF is 0 or 1.
+       ===
+
+       Each character typed returned a 1, until I typed Ctrl+d, to signify the end of
+       input, which yielded a 0. Therefor, getchar()!=EOF is 1 with all characters and
+       0 a the end of input/file. Thus, it always equals 0 or 1.
