This checkpoint proves you can take a program from nothing to running.
**The task — Personal Introduction Program.** Print a short, well-formatted
introduction of yourself:
1. A header line: === ABOUT ME ===
2. At least three fact lines in the form key: value — for example
name: Thao, goal: build Android apps, favorite number: 7. The
favorite number must come from an int variable; the key names are up
to you but every line must contain a colon followed by a space.
3. A footer line: =================
Format the number with %d (or simple concatenation). The grader checks the
header, the footer, that at least three lines contain ": ", and that one
of them ends with your favorite number. Everything else is your personality.
