C# Loops: for vs while - When to Use Each (With Real Examples)

  • Choosing between for and while loops in C# is about intent rather than syntax.
  • For loops are suitable when you know the exact number of iterations required.
  • Examples of for loop usage include processing arrays and building patterns.
  • While loops are ideal for scenarios where iterations depend on changing conditions.
  • Examples of while loop usage include user input validation and file processing.
  • Common mistakes include using while for simple counting operations and for for unknown iterations.
  • Real-world decision making involves choosing the best loop based on the specific scenario.
  • Pro tips for loop mastery include reading code aloud, considering future maintenance, and avoiding infinite loops.
  • The bottom line: Use for loops when iterations are known in advance and while loops when waiting for conditions to change.
