 A ______________ is a sequence of processing steps that may be repeated. Program loop. This represents an operation performed on data in preparation for a major sequence of operations. Preparation symbol. A ____ has two basic characteristics: 1. The loop is controlled by a counter. 2. The number of times the loop will be executed is known or preset. counter-controlled loop A more flexible approach to loop control that builds on simple counter controlled loops is called ____________ by inputting a special record before any of the regular input records. Header record logic. The SIMPLE SEQUENCE, IFTHENELSE, AND DOWHILE controls are used in _______________. structured programming. A solution algorithm should have one entrypoint and one exit point. At the same time, every basic pattern in the algorithm should also have one entry and one exit point. A computer program representation of such an algorithm can be viewed conceptually as a ________________. Single statement. A program that can be viewed as a single statement is called a(n) ________________. Proper program. SIMPLE SEQUENCE, IFTHENELSE, and DOWHILE control structures can be _______ inside other control structures. Nested. What does a loop do? Repeats steps a given number of times. A(n) ___________ is a variable that is used to hold the sum of a group of numbers. Accumulator A ________ is a special type of accumulator which adds or accumulates by a constant amount, usually 1 Counter A ____________ has two basic characteristics: 1. The loop is controlled by a counter. 2. The number of times THe loop will be executed is known or preset. Counter-controlled loop. Another name for COUNT. Loop control variable. In a DOWHILE loop, the loop steps are placed in the ____ path of the loop test? Yes To create a properly formed DOWHILE loop, you must place the loop test ___________ any other step within the loop. Before (leading decision). To create a properly formed DOWHILE loop, you must indicate that the loop will exit in the ___ path of the loop test. No. The test to determine whether the loop should be executed or exited is encountered _________________. Immediately upon entering the loop.
