________________ is a flow control statement.
In computer science, control flow (or alternatively, flow of control) is the order in which individual statements, instructions or function calls of an imperative program are executed or evaluated. Many programming languages have what are called control flow statements; used to determine what section of code is run in a program at a given time. An example of a control flow statement is an if/else statement, shown in the following JavaScript example. var x = 1; Control Flow. Alternatively referred to as flow of control, control flow (when referring to computer programming) is the order function calls, instructions, and statements are executed or evaluated when a program is running. The emphasis on explicit control flow distinguishes an imperative programming language from a declarative programming language. Within an imperative programming language, a control flow statement is a statement whose execution results in a choice being made as to which of two or more paths should be followed. We will define several keywords that enable us to control the flow of the Visual Basic program. In Visual Basic language there are several keywords that are used to alter the flow of the program. When the program is run, the statements are executed from the top of the source file to the bottom. The Select statement is a selection control flow statement. It allows the value of a variable or expression to control the flow of program execution via a multi way branch. It creates multiple branches in a simpler way than using the combination of If, Else If statements. In this example, if the variable x is set equal to 1, then the code within the curly brackets {} after the if statement is executed. Otherwise, the code within the curly brackets after the else statement is executed. This code works to control the flow of the program, depending on the value of the variable x. The While statement. The While statement is a control flow statement that allows code to be executed repeatedly based on a given boolean condition. This is the general form of the While loop: The While keyword executes the statements inside the block enclosed by the While, End While keywords. More statements can be executed inside the block, created by the If, End If keywords. We can use the Else keyword to create a simple branch. If the expression inside the square brackets following the If keyword evaluates to false, the statement following the Else keyword is automatically executed. Interrupts and signals are low-level mechanisms that can alter the flow of control in a way similar to a subroutine, but usually occur as a response to some external stimulus or event (that can occur asynchronously), rather than execution of an 'in-line' control flow statement.
