做到和现有代码解耦,代码也更容易理解了。对于大量if/else的情况也是类似来处理。
嵌套if 语句(nested if statements) 在D编程中nestif-else语句总是合法的,这意味着你可以在另一个if或else if语句中使用if或else if语句。 语法(Syntax) nested if语句的语法如下 - if( boolean_expression 1) { /* Executes when the boolean expression 1 is true */ if(boolean_expression 2) { /* E...
在Swift 4中嵌套if-else语句总是合法的,这意味着你可以使用一个ifelse ifelse if语句。 语法(Syntax) nested if语句的语法如下 - if boolean_expression_1 { /* Executes when the boolean expression 1 is true */ if boolean_expression_2 { /* Executes when the boolean expression 2 is true */ } ...

Python If Else Condition In the example above, Python executes the print statement if the condition is satisfied. However, it does not run any code if the condition is false. In this case, we can use theif-elseblock to evaluate the condition and run the else block code if the condition...
