### 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 loop “Sentinal” is a signal to the program that the loop should break
• A continue statement skips the remaining statements in loop body and proceeds with the next iteration of the loop
