looping

The process of repeating a set of instructions while a condition is true or until a condition is met.

menu

A graphical list of commands or options; in VB menus contain MenuItems that can trigger actions or shortcuts.

accumulator

A variable used to collect or sum values across loop iterations (holds the running total or combined result).

iteration

One single pass or repetition of the body of a loop.

Do While loop

A pre-test loop that repeats its body as long as a specified condition remains True (checks condition before each iteration).

infinite loop

A loop that never terminates because its exit condition is never met or the control variable is never changed.

Priming the loop

Initializing a loop control variable or input before entering a loop so the loop's condition can be evaluated correctly on the first check.

breakpoints

Debugger markers you place in code to pause execution at a specific line so you can inspect variables and program state.

CTRL

The Control key on the keyboard; used as a modifier for keyboard shortcuts (for example,Ctrl+C to copy).

*/ operator

Not a valid compound operator — a combination of multiply (*) and divide (/) symbols; compound assignment operators combine arithmetic with assignment (e.g.,+=).

blue

top-controlled

A loop that tests its condition before executing the loop body (a pre-test loop, e.g.,While ... End While).

bottom-controlled

A loop that tests its condition after executing the loop body (a post-test loop, e.g.,Do ... Loop While).

nested

A structure where one loop or control block is placed inside another loop or block (loops within loops).

debugging

The process of finding, diagnosing, and fixing errors or bugs in code using tools such as breakpoints and watches.

And

To

word used is a case statement along with the beginning and ending value to determine a range of values

Not

logical operator with the highest order of preference which allows you to state conditions that are expressed in a negative way.

Relational Operator

symbols used in a conditional like <, >, <=, and <>.

Nested

term used to describe when you place one If statement within another If statement.

Or
