An if else statement in programming is a conditional statement that runs a different set of statements depending on whether an expression is true or false.

What are if-else if and else statements How might you use them?

The if/else statement If the condition evaluates to true, JavaScript executes the code within the if block. If the condition evaluates to false, JavaScript executes code from the else block. If you need to check for more than one condition, you can use else if, which goes between if and else.

What is if-else ladder with example?

The conditional expressions are evaluated from the top downward. As soon as a true condition is found, the statement associated with it is executed, and the rest of the ladder is bypassed. If non of the conditions is true, then the final else statement will be executed.

Where is if-else used?

The if-else statement in C is used to perform the operations based on some specific condition. The operations specified in if block are executed if and only if the given condition is true. There are the following variants of if statement in C language.

What is IF AND THEN statement?

The if-then statement is the most basic of all the control flow statements. It tells your program to execute a certain section of code only if a particular test evaluates to true. For example, the Bicycle class could allow the brakes to decrease the bicycle’s speed only if the bicycle is already in motion.

What is if Elif else statement?

The if-elif-else statement is used to conditionally execute a statement or a block of statements. Conditions can be true or false, execute one thing when the condition is true, something else when the condition is false.

What is else if in programming?

Alternatively referred to as elsif, else if is a conditional statement performed after an if statement that, if true, performs a function. The above example could also be extended by adding as many elsif or else if statements as the program needed. Note. Not all programming languages are the same.

What is the difference between if-else and if Elif else statement?

The elif is short for else if. It allows us to check for multiple expressions. If the condition for if is False, it checks the condition of the next elif block and so on. If all the conditions are False, the body of else is executed.

What is the difference between if-else and ELSE IF ladder?

Nested if()else statements take more execution time (they are slower) in comparison to an if()else ladder because the nested if()else statements check all the inner conditional statements once the outer conditional if() statement is satisfied, whereas the if()..else ladder will stop condition testing once any

What is the difference between switch and else if ladder?

Switch case statement is flexible because it gives room for testing of a single expression against a list of discrete values. Else if ladder is used when there is multiple conditions are to be tested. Switch case is used when there is only one condition and multiple values of the same are to be tested.
