Exercise one: Alarm clock procedure

Description: Implement a simple alarm clock

Logic:

Seconds i++ when judging greater than or equal to 60

Minutes ++j When the judgment is greater than or equal to 60

Clock ++k to zero when judged to be greater than or equal to 24

Control output format

Points:

SETW: Setting the output width

Setfill: Setting padding content

Setprecision: Set the number of significant digits

Setiosflags: Set left or right
