Nested Loops

Nested Loops

We have seen the advantages of using various methods of iteration, or looping.
Now let's take a look at what happens when we combine looping procedures.

The placing of one loop inside the body of another loop is called nesting. When you "nest" two loops, the outer loop takes control of the number of complete repetitions of the inner loop. While all types of loops may be nested, the most commonly nested loops are for loops.

nested loops

Let's look at an example of nested loops at work.

We have all seen web page counters that resemble the one shown below ( well, OK, maybe not quite this spastic!!). Your car's odometer works in a similar manner.

This counter (if it worked properly) and your car's odometer are little more than seven or eight nested for loops, each going from 0 to 9. The far-right number iterates the fastest, visibly moving from 0 to 9 as you drive your car or increasing by one as people visit a web site. A for loop which imitates the movement of the far-right number is shown below:

for(num1 = 0; num1 <= 9; num1++)
{
cout << num1 << endl;
}

The far-right number, however, is not the only number that is moving. All of the other numbers are moving also, but at a much slower pace. For every 10 numbers that move in the column on the right, the adjacent column is incremented by one. The two nested loops shown below may be used to imitate the movement of the two far-right numbers of a web counter or an odometer:

The number of digits in the web page counter or the odometer determine the number of nested loops needed to imitate the process.

When working with nested loops, the outer loop changes only after the inner loop is completely finished(or is interrupted.).

Let's take a look at a trace of two nested loops. In order to keep the trace manageable, the number of iterations have been shortened.

for(num2 = 0; num2 <= 3; num2++)
{
      for(num1 = 0; num1 <= 2; num1++)
      {
            cout<< num2<< "   " << num1<< endl;
      }
}

Memory

Screen

int num2		int num1
	0		0
			1
			2
			3 end loop
	1		0
			1
			2
			3 end loop
	2		0
			1
			2
			3 end loop
	3		0
			1
			2
			3 end loop
	4 end loop

Remember, in the memory, for loops will register a value one beyond (or the step beyond) the requested ending value in order to disengage the loop.

0   0
0   1
0   2
1   0
1   1
1   2
2   0
2   1
2   2
3   0
3   1
3   2

Are we getting a little loopy?

The for loop

The for loop

The statements in the for loop repeat continuously for aspecific number of times. The while and do-while loops repeat until a certain condition is met. The for loop repeats until a specific count is met. Use a for loop when the number of repetition is know, or can be supplied by the user. The coding format is:

for(startExpression; testExpression; countExpression)
{
block of code;
}

The startExpression is evaluated before the loop begins. It is acceptable to declare and assign in the startExpression(such as int x = 1;). This startExpression is evaluated only once at the beginning of the loop.

The testExpression will evaluate to TRUE (nonzero) orFALSE (zero). While TRUE, the body of the loop repeats. When the testExpression becomes FALSE, the looping stops and the program continues with the statement immediately following the for loop body in the program code.

The countExpression executes after each trip through the loop. The count may increase/decrease by an increment of 1 or of some other value.

Braces are not required if the body of the for loop consists of only ONE statement. Please indent the body of the loop for readability.

CAREFUL: When a for loop terminates, the value stored in the computer's memory under the looping variable will be "beyond" the testExpression in the loop. It must be sufficiently large (or small) to cause a false condition. Consider:

for (x = 0; x <= 13; x++)
cout<<"Melody";

When this loop is finished, the value 14 is stored in x.

The following program fragment prints the numbers 1 - 20.

for:

int ctr;
for(ctr=1;ctr<=20; ctr++)
{
cout<< ctr <<"\n";
}

Common Error: If you wish the body of a for loop to be executed, DO NOT put a semicolon after thefor's parentheses. Doing so will cause the forstatement to execute only the counting portion of the loop, creating the illusion of a timing loop. The body of the loop will never be executed.

Semicolons are requiredinside the parentheses of thefor loop. The for loop is theonly statement that requires such semicolon placement.

The do-while loop

The do-while loop

The do-while loop is similar to the while loop, except that the test condition occurs at the end of the loop. Having the test condition at the end, guarantees that the body of the loop always executes at least one time. The format of the do-while loop is shown in the box at the right.

The test condition must be enclosed in parentheses andFOLLOWED BY A SEMI-COLON. Semi-colons also follow each of the statements within the block. The body of the loop (the block of code) is enclosed in braces and indented for readability. (The braces are not required if only ONE statement is used in the body of the loop.)

The do-while loop is an exit-condition loop. This means that the body of the loop is always executed first. Then, the test condition is evaluated. If the test condition is TRUE, the program executes the body of the loop again. If the test condition is FALSE, the loop terminates and program execution continues with the statement following the while.

/*The following program fragment is an input routine that insists that the user type a correct response -- in this case, a small case or capital case 'Y' or 'N'. The do-while loop guarantees that the body of the loop (the question) will always execute at least one time.*/

char ans;
do
{
       cout<< "Do you want to continue (Y/N)?\n";
       cout<< "You must type a 'Y' or an 'N'.\n";
       cin >> ans;
}
while((ans !='Y')&&(ans !='N')&&(ans !='y')&&(ans !='n'));

/*the loop continues until the user enters the correct response*/

FORMAT:

do
{
block of code;
}
while (test condition);

exit condition loop

The while loop

The while loop

The while loop allows programs to repeat a statement or series of statements, over and over, as long as a certain test condition is true. The format is shown in the box to the right.

The test condition must be enclosed in parentheses. The block of code is called the body of the loop and is enclosed in braces and indented for readability. (The braces are not required if the body is composed of only ONE statement.) Semi-colons follow the statements within the block only.

When a program encounters a while loop, the test condition is evaluated first. If the condition is TRUE, the program executes the body of the loop. The program then returns to the test condition and reevaluates. If the condition is still TRUE, the body executes again. This cycle of testing and execution continues until the test condition evaluates to 0 or FALSE. If you want the loop to eventually terminate, something within the body of the loop must affect the test condition. Otherwise, a disastrous INFINITE LOOP is the result! ;-(

The while loop is an entry-condition loop. If the test conditionis FALSE to begin with, the program never executes the body of the loop.

The following program fragment prints and counts the characters of a string array:

apstring name="Corky";
i = 0;            //begin with the first cell of array
while (i< name.length( ))    // loop test condition
{
      cout<< name[ i ] << endl;  //print each character
      i++;                            //increment counter by 1
}
cout << "There are " << i << " characters.\n";
\*This last cout prints when the test condition is false and the loop terminates*\

FORMAT:

while(test condition)
{
block of code;
}

iteration - doing the same thing again and again.

Conditional Operator

Conditional Operator

You can exchange simple if-else code for a single operator – the conditional operator. The conditional operator is the only C++ ternary operator (working on three values). Other operators you have seen are called binary operators (working on two values).

FORMAT:

conditional Expression ? expression1 :expression2;

** if the conditional Expression is true, expression1executes, otherwise if the conditional Expression is false,expression 2 executes.

If both the true and false expressions assign values to the same variable, you can improve the efficiency by assigning the variable one time:

(a>b) ? (c=25) : (c=45);

can be written as:

c = (a>b) ? 25 : 45;

if (a>b)
{
c=25;
}
else
{
c=45;
}

can be replaced with

(a>b) ? (c=25) : (c=45);

The question mark helps the statement read as follows:
"Is a greater than b? If so, put 25 in c. Otherwise, put 45 in c."

Increment and Decrement Operators

Increment and Decrement Operators

Adding or subtracting 1 from a variable is a very common programming practice. Adding 1 to a variable is calledincrementing and subtracting 1 from a variable is calleddecrementing.

increment and decrement operators work only with integer variables -- not on floating point variables or literals.
the C++ compiler is controlling the execution of the prefix and postfix operators. You cannot change this order of execution. For example, the parentheses below will not force an early execution:
value = (((x--)))* num; //still decrements x last.
one disadvantage of using the increment/decrement operators is that the variable can only be incremented or decremented by the value ONE. If you need to increment (or decrement) by a larger (or smaller) value, you must use statements like
m += 2; or amount -= 5;
be careful when combining increment and decrement operators inside expressions with logical operators. If in doubt, don't use them together. For example, do NOT use:
if (( num1 = = 4 ) || ( num2 != ++j)) (j may not be incremented when (num1 = = 4) is TRUE.)Instead, separate the code to avoid this problem:
++j;
if (( num1 = = 4) || (num2 != j))

All are the same:i = i + 1;
i += 1;
i++;

Prefix:
++i;
--i;increment or decrement occurs before the variable's value is used in the remainder of the expression.

Postfix:
i++;
i--;increment or decrement occurs after the variable's value is used in the remainder of the expression.
