How to resolve the algorithm Conditional structures step by step in the FreeBASIC programming language

Table of Contents

Problem Statement

List the conditional structures offered by a programming language. See Wikipedia: conditionals for descriptions. Common conditional structures include if-then-else and switch. Less common are arithmetic if, ternary operator and Hash-based conditionals. Arithmetic if allows tight control over computed gotos, which optimizers have a hard time to figure out.

Let's start with the solution:

Source code in the freebasic programming language

Dim a As Integer = 1
If a = 1 Then
  sub1
ElseIf a = 2 Then
  sub2
Else
  sub3
End If

Dim a As Integer = 1
Select Case a
  Case 1
    sub1
  Case 2
    sub2
  Case Else
    sub3
End Select

Dim b As Boolean = True
Dim i As Integer = IIf(b, 1, 2)

Dim a As Integer = 1
On a Goto label1, label2

Dim b As Boolean = True
If b Goto label

Dim a As Integer = 1
On a Gosub label1, label2
