| 66 | <p>C accepts aliases for certain characters. Apparently in the 1990s
|
|---|
| 67 | some computer systems had trouble inputting these characters, or
|
|---|
| 68 | trouble displaying them. These digraphs almost never appear in C
|
|---|
| 69 | programs nowadays, but we mention them for completeness.
