First, the word pollution implies that something is bad or negative in some way. Furthermore, all studies agree that pollution is a problem; they simply disagree on the impact it will have or the scope of the problem.This problem has been solved! See the answer.

Flow of Control Repetition: used for looping, i.e. repeating a piece of code multiple times in a row. In this case, notice the compound statement to delineate the bodies of the if and else clauses. This also means the case label must be a literal or a variable declared to be const.Essentially, a control structure is a "block" of code that analyzes variables and chooses a direction in which to go based on given parameters. There exist essentially two kinds of control structures. In the second example, we use an if statement to assess if x is an even number and, if this is the case...

A control structure is any mechanism that departs from the default of straight-line execution. » selection. • if statements • case statements.

Compound statements contain (groups of) other statements; they affect or control the A suite is a group of statements controlled by a clause. A suite can be one or more semicolon-separated simple statements on The while statement is used for repeated execution as long as an expression is trueControl Structure. Normally, a program is executed in a sequential manner.However, in many cases, a program has to choose among alternative statements C++ provides constructs that enable the This is called transfer of control. Flowcharts: • A flowchart is a graphical representation of an algorithm....of statements to repeat. a. decision statement b. constant loop c. cout object d0 None of these. This is because it will iterate continuously and indefinitely. While loop: Also referred to as a Pretest loop Answer: D. None of these. Explanation: The control structure that causes a statement or a...This chapter shows you how to structure the flow of control through a PL/SQL program. You learn how statements are connected by simple but powerful control structures that have a single The iteration structure executes a sequence of statements repeatedly as long as a condition holds true.The other type of important programming control structure is a repetition statement. A repetition statement is used to repeat a group (block) of programming instructions. Most beginning programmers have a harder time using repetition statements than they have at using selection statements.

2 Loops A control structure that causes a statement or group of statements to be finished repeatedly There are 3 sorts of loops –whilst –for –do whilst

> inputVal;"> 3 The While Statement while (expression) Statement while (inputVal != 25) cin >> inputVal;

> inputVal;" title="The While Statement while (expression) Statement while (inputVal != 25) cin >> inputVal;">

4 whilst and if Not the same construct If statements do not repeat While statements will repeat till the expression becomes false While statements must all the time have a statement that will in the end make the expression to transform false

5 Phases of Loop Execution Loop entry – The level at which of the low of control reaches the first statement inside a loop. Iteration – An individual cross through or repetition of, the frame of a loop. Loop check – The point at which the While expression is evaluated and a determination is made both to start a new iteration or skip to the statement straight away following the loop. Loop exit – the point at which the repetition of the loop ends and control passes the first statement following the loop. Termination situation – The situation that causes the loop to be exited.

18 Remembering Loop count = 0; in.get ( prevChar ); in.get ( currChar ); whilst ( !in.eof() ) if ( currChar == '=' && prevChar == '!' ) rely++; prevChar = currChar; in.get( currChar );

19 Designing Loops What is the situation that ends the loop? How should the condition be initialized? How should the condition be up to date? What is the method being repeated? How must the method be initialized? How will have to the method be updated? What is the state of this system on exiting the loop?
