CHAPTER 4 : Looping Statements
Definition
Looping is a sequence of instructions that is continually repeated until a certain condition is reached .
A loop is a way of repeating a statement a number of times until some way of ending the loop occurs .
3 types of looping statements
FOR
WHILE
DO-WHILE
Define Loop Statement
For : Programming language statement which allows code to be repeatedly executed
While : Control flow statement
Do-while : Control flow statement
Break Statements
Statement allows you to exit a loop from any point within its body,bypassing its normal termination expression
Used in conjuction with functions and case statements which have been covered in previous session
Continue Statements
Cause control to go directly to the test condition and then continue the looping process
One good use of Continue is a to restart a statement sequence when an error occurs
Goto Statements
Create a loop by jumping backwards to a label though this is generally discouraged as a bad programming practice
Differentiate the loop statements
WHILE : Loop the condition is tested first and then the statements are executed if the condition turn out to be true
DO-WHILE : Statements are executed for the first time and then the conditions are tested,if the condition turns out to be true then the statements are executed again
FOR : Allowing us to repeat certain parts of the program until a specified number of repetitions - allows to determine the required number of repetitions
