JavaScript else if Statement : Programming Foundations #09
JavaScript else if Statement : Programming Foundations #09
JavaScript else if and if statements are used when making programming decisions. By now, you already know about the JS while loop and using conditionals in looping. Similar to the while loop, the if/else if statement also uses a conditional to determine a decision.

[freeCodeCamp] Basic JavaScript - Conditional Logic, Logical Operators, switch statement
This post covers various ways, one can implement the conditional logic and use the logical operators in JavaScript. This also provides an update on my JavaScript learning from @freecodecamp. #javascript #100daysofcode #webdev #js
Hey fellas! Guess what? This time we are going to dive into one of the main concepts in any programming language i.e. implement conditional logic. This is in continuation of my JavaScript learning from freeCodeCamp. We’ve learned quite a few concepts in the series and going to know more about them.
In the previous post in the series, we learned about Boooleanand comparison operators which are…

Sometimes, one requires to execute some of the conditional codes. For this, you can use if else statement in Matlab. Check its syntax and examples.
Have a look at our latest blog on how to create an if else statement in MATLAB
SELECTION STATEMENTS
Our professor also discussed about selection statements which includes if and else and switch.
So an if statement can be followed by an optional else statement, which executes when the boolean expression is false.
If the boolean expression evaluates to true, then the if block of code will be executed, otherwise else block of code will be executed.
EXAMPLE
When the above code is compiled and executed, it produces the following result:
if...else if...else Statement
An if statement can be followed by an optional else if...else statement, which is very useful to test various conditions using single if...else if statement.
When using if , else if , else statements there are few points to keep in mind.
-An if can have zero or one else's and it must come after any else if's.
-An if can have zero to many else if's and they must come before the else.
-Once an else if succeeds, none of he remaining else if's or else's will be tested.
EXAMPLE
When the above code is compiled and executed, it produces the following result:
A switch statement allows a variable to be tested for equality against a list of values. Each value is called a case, and the variable being switched on is checked for each case.
The following rules apply to a switch statement :
>The expression used in a switch statement must have an integral or enumerated type, or be of a class type in which the class has a single conversion function to an integral or enumerated type.
>You can have any number of case statements within a switch. Each case is followed by the value to be compared to and a colon.
>The constant-expression for a case must be the same data type as the variable in the switch, and it must be a constant or a literal.
>When the variable being switched on is equal to a case, the statements following that case will execute until a break statement is reached.
>When a break statement is reached, the switch terminates, and the flow of control jumps to the next line following the switch statement.
>Not every case needs to contain a break. If no break appears, the flow of control will fall through to subsequent cases until a break is reached.
A switch statement can have an optional default case, which must appear at the end of the switch. The default case can be used for performing a task when none of the cases is true. No break is needed in the default case.
EXAMPLE
Thia would produce the following result:
else if question in c output of the following program
else if question in c output of the following program
else if question in c output of the following program else if question in c output of the following program

Programlama Temelleri – if-else-if ardışık sorgulama
İf -else yapısında bir şartın sağlanması durumunda veya sağlanmaması durumunda yapılması gerekenler tanımlanmaktaydı. İf else yapısı bir bütünü farklı aralıklarla parçalara ayırmak gerektiği durumlardaki sorgularda avantaj sağlamak için tasarlanmıştır. Örneğin; bir öğrencinin aldığı notlara göre geçme kalma değerlendirmesi yapalım. Alınan not 0-50 aralığındaysa sonuç farklı, 50-60 aralığındaysa…
