Glossary Glossary
- algorithm.
- A step-by-step process for solving a category of problems.
- body.
- The indented statements after a heading ending in a colon, for instance after a for-loop heading.
- counter.
- A variable used to count something, usually initialized to zero and incremented in the body of a loop.
- cursor.
- An invisible marker that keeps track of where the next character will be printed.
- definite iteration.
- A loop where we have an upper bound on the number of times the body will be executed. Definite iteration is usually best coded as a
forloop. - escape sequence.
- An escape character, \, followed by one or more printable characters used to designate a nonprintable character.
- generalize.
- 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. - iteration.
- Repeated execution of a set of programming statements.
- loop.
- 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. We will work more on nested loops in Chapter 10.
- newline.
- A special character that causes the cursor to move to the beginning of the next line.
- reassignment.
- Making more than one assignment to the same variable during the execution of a program.
- tab.
- A special character that causes the cursor to move to the next tab stop on the current line.
- traverse.
- To iterate through the elements of a collection, performing a similar operation on each.
