1 Chapter 4: Control structures Repetition
2 Loop Statements After reading and studying this Section, student should be able to Implement repetition control in a program using while statements. Implement repetition control in a program using do-while statements. Implement a generic loop-and-a-half repetition control statement Implement repetition control in a program using for statements. Nest a loop repetition statement inside another repetition statement. Choose the appropriate repetition control statement for a given task Page 2
3 Definition Repetition statements control a block of code to be executed for a fixed number of times or until a certain condition is met. There are three types of repetition: Count-controlled repetitions terminate the execution of the block after it is executed for a fixed number of times. Sentinel-controlled repetitions terminate the execution of the block after one of the designated values called a sentinel is encountered. Flag-controlled repetitions terminate the execution of the block after one of the designated values called a sentinel is encountered. Repetition statements are called loop statements also. Page 3
4 The while Statement int sum = 0, number = 1; while ( number <= 100 ) { sum = sum + number; number = number + 1; These These statements statements are are executed executed as as long long as as number number is is less less than than or or equal equal to to Page 4
5 Syntax for the while Statement while ( <boolean expression> ) <loop body> Boolean Expression while ( number <= 100 ) { loop body sum = sum + number; number = number + 1; Page 5
6 Control Flow of while int int sum sum = 0, 0, number number = 1 number <= <= ? true false sum sum = sum sum + number; number = number + 1; 1; Page 6
7 More Examples 1 int sum = 0, number = 1; while ( sum <= ) { sum = sum + number; number = number + 1; Keeps Keeps adding adding the the numbers numbers 1, 1, 2, 2, 3, 3, until until the the sum sum becomes becomes larger larger than than 1,000,000. 1,000, int product = 1, number = 1, count = 20, lastnumber; lastnumber = 2 * count - 1; Computes Computes the the product product of of the the first first odd odd integers. integers. while (number <= lastnumber) { product = product * number; number = number + 2; Page 7
8 Loop Logical Errors 1 Goal: Execute the loop body 10 times. count = 1; while ( count < 10 ){... count++; 2 count = 1; while ( count <= 10 ){... count++; 3 count = 0; while ( count <= 10 ){ 4 count = 0; while ( count < 10 ){ count++; count++; 1 and 3 exhibit off-by-one error. Page 8
9 The do-while Statement int sum = 0, number = 1; do { sum += number; number++; These These statements statements are are executed executed as as long long as as sum sum is is less less than than or or equal equal to to 1,000,000. 1,000,000. while ( sum <= ); Page 9
10 Syntax for the do-while do Statement <loop body> while ( <boolean expression> ) ; do { sum += number; number++; loop body while ( sum <= ); Boolean Expression Page 10
11 Control Flow of do-while int int sum sum = 0, 0, number number = 1 sum sum += += number; number++; sum sum <= <= ? true false Page 11
12 The for Statement int i, sum = 0, number; for (i = 0; i < 20; i++) { number = scanner.nextint( ); sum += number; These These statements statements are are executed executed for for times times (( i i = 0, 0, 1, 1, 2, 2,,, 19). 19). Page 12
13 Syntax for the for Statement for ( <initialization>; <boolean expression>; <increment> ) <loop body> Initialization Boolean Expression Increment // Decrement for ( i = 0 ; i < 20 ; i++ ) { number = scanner.nextint(); sum += number; loop body Page 13
14 Control Flow of for i i = 0; 0; false i i < 20 20? true number =...;; sum sum += += number; i i ++; ++; Page 14
15 More for Loop Examples 1 for (int i = 0; i < 100; i += 5) i i = 0, 0, 5, 5, 10, 10,,, for (int j = 2; j < 40; j *= 2) j j = 2, 2, 4, 4, 8, 8, 16, 16, for (int k = 100; k > 0; k--) ) k = 100, 99, 99, 98, 98, 97, 97,...,..., 1 Page 15
16 The Nested-for Statement Nesting a for statement inside another for statement is commonly used technique in programming. Let s generate the following table using nested-for statement. Page 16
17 Generating the Table int price; for (int width = 11; width <=20, width++){ for (int length = 5, length <=25, length+=5){ OUTER INNER price = width * length * 19; //$19 per sq. ft. System.out.print ( + price); //finished one row; move on to next row System.out.println( ); Page 17
