What is the difference between else if and if else?
So as the default case handles all possibilities the idea behind else if is to split this whole rest into smaller pieces. The difference between else and else if is that else doesn’t need a condition as it is the default for everything where as else if is still an if so it needs a condition.
How does if and else if work?
The if/else statement executes a block of code if a specified condition is true. If the condition is false, another block of code can be executed. Use if to specify a block of code to be executed, if a specified condition is true. Use else to specify a block of code to be executed, if the same condition is false.
Can if and else if both be executed?
No, they won’t both execute. It goes in order of how you’ve written them, and logically this makes sense; Even though the second one reads ‘else if’, you can still think of it as ‘else’. If your first statement is true, you don’t even bother looking at what needs to be done in the else case, because it is irrelevant.
Can you put an if else inside an if else?
Yes, placing an if inside an else is perfectly acceptable practice but in most cases use of else if is clearer and cleaner. E.g. and the two should compile to almost identical programs in most situations.
What is the difference between if else and switch case?
In the case of ‘if-else’ statement, either the ‘if’ block or the ‘else’ block will be executed based on the condition. In the case of the ‘switch’ statement, one case after another will be executed until the break keyword is not found, or the default statement is executed.
Which is better if or else if?
A switch statement is usually more efficient than a set of nested ifs. if-else better for boolean values: If-else conditional branches are great for variable conditions that result into a boolean, whereas switch statements are great for fixed data values.
