The if-then and if-then-else Statements Theif-thenStatement Theif-thenstatement is the most basic of all the control flow statements. It tells your program to execute a certain section of codeonly ifa particular test evaluates totrue. For example, theBicycleclass could allow the brakes to de...

Is it posiible to create a function using if (xxxx=A) then {do something} else {do something else} in a model or in a controller? The validation rules in a model operate in checking the input of a single field. But in order to make a decision and control the flow of an app is...
An improvement over deeply nested IF-THEN-ELSE control structures This paper describes an alternative to deeply nested IF-THEN-ELSE control structures within high-level language programs. This alternative improves the maintainability and extensibility of programming technique uses a CASE or SELECT cont.....
This chapter presents the DO loop, the IF–THEN–ELSE, and the WHILE loop. A DO loop is in general easier to use than the GO TO and IF; moreover, it is also easier for someone reading the program to understand. To follow a GO TO statement, one either has to go back to a previo...
This paper introduces the following new constructions on stable event structures: the tensor product, the linear function space, and the exponential. It results in a monoidal closed category of stable event structures which can be used to interpret intuitionistic linear logic....
Our approach is a semantic and semiotic reading related to aesthetics, always operating at this metalevel of language. Approaching art in this manner leads us to the codes and structures of the system ‘art’ which operate between the signified and the signifier. But by declaring what we alread...

Sometimes you also need to repeat the same set of statements repeatedly. Such statements are called loops. The number of times you do this may be or may not be known at the time of writing a program. This will lead us to for, while, and Do While loops.
