Introduction to Selection IF Statement
The if statement evaluates the test expression within parenthesis. If the test expression is true, statements inside the body of if is executed. If test expression is evaluated to false, statements within the body of if is skipped. CITATION pro19 l 2057 (programiz, 2019)IF ELSE Statement
The if else executes the codes within the body of if statement if the check expression is true and skips the codes inside the body of else. If the check expression is false, it executes the codes within the body of else statement and skips the codes inside the body of if. CITATION pro19 l 2057 (programiz, 2019)NESTED IF ELSE Statement The if…else statement executes two different codes depending upon whether the test expression is true or false. Sometimes, a choice has to be made from more than 2 possibilities.
The nested if…else statement allows you to check for multiple test expressions and execute different codes for more than two conditions. CITATION pro19 l 2057 (programiz, 2019)Switch CaseA switch statement allows a variable to be tested for equality against a list of values. Each value is called a case, and the variable being switched on is checked for each case.
A ternary operator operates on 3 operands which may be used as an alternative of an if…else statement.
CITATION Par19 l 2057 (Parewa Labs Pvt. Ltd., n.d.)RepetitionFor LoopA for loop is a repetition control structure that allows you to efficiently write a loop that needs to execute a specific number of times. CITATION Tut19 l 2057 (Tutorialspoint, n.d.)While LoopA while loop statement repeatedly executes a target statement as long as a given condition is true. CITATION Tut191 l 2057 (Tutorialspoint, n.d.)Do While LoopThis loop is similar to a while loop, apart from that a do…while loop is guaranteed to execute at least one time. CITATION Tut192 l 2057 (Tutorialspoint, n.d.)Introduction to modularization
