What is Difference between if statement and select case statement in vbscript?
If statements and Select-Case statements are two similar features that allow for code branching. The difference is that each If statement may compare against different variables and different ranges, while Select-Case statements may only compare against one variable at a time, and must compare against discrete values. Select-Case is therefore a specialized form of If statements, and are more efficient in terms of amount of code used and execution speed when used instead of theequivalentIf-Else statements.
What is the difference between If-else and Switch-case in Java?
The if statement is used to select among two alternatives. It uses a boolean expression todecide which alternative should be executed. The switch statement is used to select among multiple alternatives. It uses an int expression to determine which alternativeshould be executed.

What is the use of break in c programming?

If the switch statement does not have a case label for every value it will cause a runtime error?
There might be unexpected effects, due to the fact that the programmer didn't consider other cases. It is usually safest to set up a default case for "all other values". This would go at the end. Check the syntax for the specific programming language you are using. In some programming languages, omitting this default statement may also generate a compile-time error, at least in certain cases, when the compiler determines that after the switch statement a variable may not have a definite value - and that value is later used. In some programming languages this is known as the "definite assignment rule".
Which keyword should be used in a SELECT statement to retrieve only parts of the result set?
