A variable used to count something, usually initialized to zero and incremented in the body of a loop.
An invisible marker that keeps track of where the next character will be printed.

- escape sequence
An escape character, \, followed by one or more printable characters used to designate a nonprintable character.
To replace something unnecessarily specific (like a constant value) with something appropriately general (like a variable or parameter). Generalization makes code more versatile, more likely to be reused, and sometimes even easier to write.
- infinite loop
A loop in which the terminating condition is never satisfied.
- indefinite iteration
A loop where we just need to keep going until some condition is met. A
whilestatement is used for this case.
Repeated execution of a set of programming statements.
A statement or group of statements that execute repeatedly until a terminating condition is satisfied.
- loop variable
A variable used as part of the terminating condition of a loop.
- nested loop
A loop inside the body of another loop.
