If expression1 is true, the whole ternary statement returns expression2. In this syntax, expression1 must return a value of true or false. Here is the syntax for the ternary operator: By contrast, an if statement provides conditional branching of the program flow but can't be assigned to a variable. The result can be assigned to a variable. The ternary operator ( ?) is a conditional statement that is resolved to one of two expressions. Code segment B (the values are comma-delimited) If you do not use the break statement, the program flow in the switch statement continues into the next case. If x is 10, b is assigned to a, and d is assigned to c. The following code example makes the execution drop through the first case branch by omitting a break statement. As shown in the following example, if the Debtor account number is 1000, the program executes "do something", and then continues execution after the switch statement. When you include the break keyword in a switch statement, the execution of the case branch terminates, and the statement following the switch is executed. Here is the syntax for a switch statement: If there are no matches and no default statement, none of the statements inside the switch statement are executed.If no matches are found, the default statement is executed.If the case doesn't contain a break statement, the program continues and executes the next case statements.If the case contains a break statement, the program then jumps out of the switch.If a case constant matches the switch expression, the case statement is executed.The case values must be constants that the compiler can evaluate. The expression of the switch statement is evaluated and checked against each case value. The switch statement is a multibranch language construct that has the same behavior as nested if. Examples of if and if.else statements // if statement However, if the nesting of if statements becomes too deep, you should consider using a switch statement instead. The expression in the parentheses (the conditional expression) can be any valid expression that is evaluated as true or false. In this syntax, both occurrences of statement can be compound statements (statements enclosed in braces). You can use the else clause to provide an alternative statement or set of statements that is executed if the condition is evaluated as false. The if statement evaluates a conditional expression, and then executes a statement or a set of statements if the conditional expression is evaluated as true. Different conditional statements offer advantages in different situations. You use conditional statements to specify whether a block of code is executed. else, switch, and the ternary operator ( ?). This article describes conditional statements in X++.
