Thanks for a great lesson, Profr. Hillstrom; no doubt the more one practices the easier it gets to learn this and other languages. They all have similar structures. It's the syntaxis which gets tedious.

Loops

  • Loops, or repetition statements, repeat blocks of code without the programmer having to re-type them
  • Loops usually use Counters to count the number of times the loop has run
  • Counters usually use Increment and Decrement operators to add or subtract from the counter total
  • A continue statement skips the remaining statements in loop body and proceeds with the next iteration of the loop
