What is the problem with IF statements?

Explanation: It is possible to have multiple ELSIF parts within one IF – END IF block. The IF statement can have multiple ELSIF parts but can have only one ELSE statement part. ELSE part will be executed after each of the ELSIF part is checked and found to be FALSE.

What is the disadvantage of IF THEN statement?

If indenting is not proper maintained then it is difficult to debugging because a programmer faces difficulty associate statement to related block. Else-if leader does not specify better interpretation of business logic to programmer than switch case.

Why are else if statements Bad?

The problem with if statements is that novice (or just bad) programmers over use them when other constructs would be more suitable. Too often, such programmers create baroque and fragile structures out of chains of if-elif-else or deeply nested if-else or both.

What is not true about if else if statement?

if..else statements

In an if...else statement, if the code in the parenthesis of the if statement is true, the code inside its brackets is executed. But if the statement inside the parenthesis is false, all the code within the else statement's brackets is executed instead.

Why we should avoid if else?

Avoid if-else When Assigning Value to a Variable

While it might not seem bad, you could easily end up inverting or tweaking the conditional logic to give a whole new meaning. The branching logic also brings a little code duplication, as we're assigning the variable num in multiple blocks, which is not necessary.

Why if else is not working?

If you are getting an error about the else it is because you've told the interpreter that the ; was the end of your if statement so when it finds the else a few lines later it starts complaining. A few examples of where not to put a semicolon: if (age < 18); if ( 9 > 10 ); if ("Yogi Bear".

What are the limitations of switch statement?

Disadvantages of switch statements

float constant cannot be used in the switch as well as in the case. You can not use the variable expression in case. You cannot use the same constant in two different cases. We cannot use the relational expression in case.

What is the advantage of else if ladder?

Advantages: In computer programming, situations involving series of decisions one after the other, each decision or condition may involve expression of various data types such as float, integer, char and double. In these situations the if-else-if ladder is used.

What is meant by compound condition?

Compound Condition. A type of condition in which more than one conditions are evaluated is called compound condition. It is used to execute a statement or set of statements by testing many conditions.

Can we write if statement without else?

An if statement looks at any and every thing in the parentheses and if true, executes block of code that follows. If you require code to run only when the statement returns true (and do nothing else if false) then an else statement is not needed.

How do you reduce if-else statements?

Avoid using nested if-else statements. Keep the code linear and straightforward. Utilize creating functions/methods. Compare it when we try to use an if-else statement that is nested and that does not utilize the power of the return statement, We get this (Code 1.4).

What can I use instead of if statements?

Conditional branching can introduce complexity into a program. Nested if and switch statements can make code less readable and open potential for bugs.
