A key question in code, computer science, and the universe is whether to use a return in an else-block.

If you didn't have the "else" part, what would it return when the boolean expression is false? Thank you anyway. While using this site, you agree to have read and accepted our In If Else statement, we have one more block, called else block, which executes when the condition is false. If the case was false, there would be no defined assignment.gcc allows some sort of special case for this but it's a non-standard extension. W3Schools is optimized for learning, testing, and training. Stack Overflow works best with JavaScript enabled If condition is false, the else-statement runs. This can be achieved in C++ using if-else statement. The if statement may have an optional else block. I was just wondering if there was a way to not implement the either part if all you care about is when the condition evaluates a certain way, otherwise do nothing. In an if-else statement, if condition evaluates to true, the then-statement runs.

Example explained. In the example above, time (22) is greater than 10, so the first condition is false.The next condition, in the else if statement, is also false, so we move on to the else condition since condition1 and condition2 is both false - and print to the screen "Good evening". You can do the same thing with the if...else..if ladder.

However, if the time was 14, our program would print "Good day." In my case, I was looking if it is possible to shorten If embedded as the Right Value of an assignment, then the assignment must take place and so the 'other case' of the expression evaluates to and assigns the value of the shortcut condition: 1 for || and to 0 for &&.

@PaulR I remember reading that somewhere, but I never looked into it. Although, I suppose it does make sense in the case of an assignment using this statement.

If the condition is true, if block is executed, and if the condition is false, else block is executed. If the number is not even, in the else block, we shall print to the console that number is odd. If the In the following example, we have an if-else with condition to check whether the number is even.

The switch statement allows us to execute one code block among many alternatives. C# supports the usual logical conditions from mathematics:You can use these conditions to perform different actions for different decisions.In the example below, we test two values to find out if 20 is greater than The syntax of an if...else statement in C++ is − if(boolean_expression) { // statement(s) will execute if the boolean expression is true } else { // statement(s) will execute if the boolean expression is false } So, in C if-else statement, we have an if block followed by else block. The syntax is correct, my example implementation was faulty; that is not the point of this question. This is if block, and have just a single statement. In this tutorial, we will learn about the C++ if...else statement and its use in decision making programs with the help of examples. C has the following syntax for a shorthand IF-ELSE statementI often find myself requiring only one portion (TRUE or FALSE) of the statement and use thisI was just wondering if there was a way to not include the ELSE portion of the statement using this shorthand notation? ... ... whilst technically not an if-else per se, the behaviour is the same and avoids the clunky approach of using the choose tag, so depending on how complex your requirement is this might be preferable. The syntax of the if..else statement is: if (test expression) { // statements to be executed if the test expression is true } else { // statements to be executed if the test expression is false } 0 : n, but why not just say if (i==5) n=0; which is nice and short (shorter - even with single char var). In this tutorial, you will learn to create the switch statement in C programming with the help of an example. Stack Overflow for Teams is a private, secure spot for you and

Alternatively you can use n = (i==5)? By clicking “Post Your Answer”, you agree to our To subscribe to this RSS feed, copy and paste this URL into your RSS reader. Another form of if else - Ternary Operator
