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
