It is easy to edit switch cases as, they are recognized easily. The if-else statements belong to selection statements in OOP.
The general form of the if-else statements is as follow. The expression in if statement can contain an integer, character, pointer, floating-point or it can be a boolean type. The else statement is optional in an if-else statement.
If the expression returns true, the statements inside if statement is executed, and if it returns false the statements inside else statement are executed and, in case an else statement is a not created no action is performed, and the control of the program jump out of an if-else statement. Here, the if statement evaluates the equality along with the logical evaluation.
If the expression would have return false, then the statement in an else statement would have been executed. The switch statements is a multiple-choice selection statement. The general form of the switch statement is as follow. Where the expression evaluates an integer or character constants. A break statement tends to be optional in a switch statement. But the absence of a break statement will result in a nonstop execution until the end of the switch statement.
Switch statement normally uses keyboard commands and the expression usually contain a single expression. Programing language tends to be difficult for beginners and it is recommended to understand terms such as if-else and switch-case statements. Improve this answer.

One note to mention that the case fall through behaviour is language spcific, c will happily allow you do do this but c places some restrictions on falling through one case statement to another.
IF else - IT is used for taking a decisions Switch statement - It is used to test the value of the given variable against a list of case value. Kv mathew Kv mathew 49 1 1 bronze badge. Both are used for testing values, and both are used for taking decisions. You can't take a decision without testing a value, and testing a value is pointless unless you are going to take a decision.
Differences Between if-else and switch Expression inside if statement decide whether to execute the statements inside if block or under else block. No default there. And 1 is a distinction without a difference. There is no essentiall difference here. Advantages of switch over if-else ladder: A switch statement works much faster than equivalent if-else ladder. It is because compiler generates a jump table for a switch during compilation.
Consequently, during execution, instead of checking which case is satisfied, it only decides which case has to be executed. It is more readable and in compare to if-else statements.

If we remove any of the cases from the switch, then it will not interrupt the execution of other cases. Therefore, we can say that the switch statement is easy to modify and maintain. The case constants in the switch statement create a jump table at the compile time. This jump table chooses the path of the execution based on the value of the expression.
If we have a multiple choice, then the execution of the switch statement will be much faster than the equivalent logic of 'if-else' statement. JavaTpoint offers too many high quality services.
