What is the use of Default statement in switch case?
C++ Provides a multiple branch selection called as switch. This selection statement succesively test against a list of integer or character constants. When a match is found the statements associate with constants are executed. When no match is found default statement is used.
How do you choose multiple if statement and switch statement?
If you must evaluate two or more expressions separately, use multiple if statements. If you only need to test all the possible evaluations of a single expression, use a switch.
What optional statement can be used in a case structure to execute statements when all other conditions are false?
default : <statement>; i.e. switch (value) { case 1 : do_this(); break; case 2 : do_that(); break; default : do_whatever(); }
What does default mean in switch statement?
Default clause in switch statement used to indicate that the desired option is not available with the switch case statement. it is similar to else statement of if statement which is used when the condition does not satisfy.
What is the similarity between 'if' statement ans 'switch' statement?
A Switch statement can be considered as a series of if. else if. else statements. whatever condition is satisfied, the code block would get executed. if (cond 1) { } else if (cond 2) { } else if (cond 3) { } ...... } else if (cond N) { } else { } switch { case 1: .... case 2: .... .... case N: ... default: ... } Difference: In the if else blocks, if one condition is satisfied, all other blocks are ignored In Switch blocks, unless you have break statements inside each condition block, the subsequent blocks would not be ignored.

What is the difference between 'switch' statement and 'if' statement?
we can use switch statement in multiple time but in if statement we can not use multiple time

How do you use a switch statement in GML?
Switch Statements are used to generate different outputs of code based on the value of an expression. Switch Statements work as follows:{randomNumber = floor(random(3))+1;switch(randomNumber) {case 1: { } break;case 2: { } break;case 3: { } break;default: { } break;}}This may seem confusing if you are new to GML, so I will give an in-depth explanation. The first line sets the variable randomNumber to a random number between 0 and 2, and adds it by 1 to make it a random number from 1-3. So far the only thing that has gone on in the code is to set a variable to either 1, 2, or 3. This is where the switch statement comes in.switch(randomNumber) {case 1: { } break;case 2: { } break;case 3: { } break;default: { } break;}this is the actual switch statement. You may be wondering what the case statements are for. case statements are always written inside switch statements and do nothing anywhere else. case statements activate when the expression in the switch statement is the same as the value that they are assigned to. Take a look at this switch statement:{rand = floor(random(3));switch(rand) {case 0: {show_message("The Random Value Was 0");} break;case 1: {show_message("The Random Value Was 1");} break;case 2: {show_message("The Random Value Was 2");} break;}} When the values assigned to the case statements are equal to the expression in the switch statement, the case statement will run the code contained in it's brackets. break statements order the switch statement to abort. The reason that you need break statements inside a switch statement is because it keeps the other cases from activating as well. (When one case statement activates, the others do as well.)A final briefing on switch statements is that they are not limited to variables. Take a look at this switch statement.{switch(obj_block.x > x) {case true: {show_message("The Block Is Ahead Of You.");} break;case false: {show_message("You Are Ahead Of The Block.");} break;}} This switch statement returns a true or false value, and the case statements operate accordingly.
What is different conditional statement give it's syntax and example?
A different conditional statement, also known as a "switch" statement, allows for multiple conditions to be evaluated without the need for multiple if statements. Its syntax typically includes a variable to evaluate, followed by case clauses and a default case. Here’s an example in JavaScript: let fruit = "apple"; switch (fruit) { case "banana": console.log("It's a banana."); break; case "apple": console.log("It's an apple."); break; default: console.log("Unknown fruit."); } In this example, the output will be "It's an apple." since the variable fruit matches the second case.
What is the similarity between 'if' statement ans 'switch' statement?
A Switch statement can be considered as a series of if. else if. else statements. whatever condition is satisfied, the code block would get executed. if (cond 1) { } else if (cond 2) { } else if (cond 3) { } ...... } else if (cond N) { } else { } switch { case 1: .... case 2: .... .... case N: ... default: ... } Difference: In the if else blocks, if one condition is satisfied, all other blocks are ignored In Switch blocks, unless you have break statements inside each condition block, the subsequent blocks would not be ignored.
What is the deffernce of the switch statement and the if statement in c plus plus?
If statement is single selection statement,whereas the switch statement is multiple selective.
In computer programming what is the difference between a switch and a transistor?
In the general subject of computer programming neither switch nor transistor exist as concepts. They are out of scope.The language C (and its relatives) have a switch statement, but still no concept of transistor.The switch statement of C is a statement in the general class of multiple way decision statements (aka multiple way branch statements) and are called other things in other languages:FORTRAN IV - computed GOTO statementFortran 95 - case constructBASIC - ON ... GOTO statementCOBOL - EVALUATE statementPL/1 - SELECT statementPascal - case statementAda - case statementetc.
How if else if statement is differ from switch in general in java?
An else statement is comparing to items, while a switch statement is used to compare multiple items. So if you need multiple results from one statement use a switch but for booleans or very specific functions use a if else statement. Else If ex. if(a=6){System.out.println("It is six");} else(){System.out.println("It is not six");} Switch ex. switch(a){ case 1: System.out.println("it is one"); break; case 2: System.out.println("it is two"); break; default: System.out.println("it is not one or two"); break; } Basically a switch is a good way to check against a lot of possibilities.
What is the format of the switch statement?
switch (expression) { case value 1 : [ statement-block 1] [break ;] case value 2 : [ statement-block 2] [break ;] ……. ……. case value N : [ statement-block N] [break ;] [default: [default block] [break;] ] } statement x;
