Video Description
Computers excel at repetition! Master the three types of loops and learn when to use each one.
What you'll learn:
- For loops - when you know the count
- While loops - when count is unknown
- Foreach loops - cleanest for collections
- Do-while - execute at least once
- Break and continue for flow control
- Nested loops for 2D data
- Avoiding infinite loops
- Common loop patterns (searching, accumulating, filtering)
- Performance considerations
When to use each:
- For: Known iterations, need index
- While: Unknown iterations
- Foreach: Process collections cleanly
- Do-While: Menus and "at least once" scenarios
