If condition Then statements Else statements End If
What happens when an If test is met in a nested If…Then…Else structure?
The code associated with that condition is executed and the If block is exited
What is the purpose of using nested If…Then…Else structures?
To test for multiple cases by placing If…Then…Else structures inside If…Then…Else structures
Why is it important to consider all viable possibilities in an If/Else/End If structure?
To ensure that all possible conditions are tested
When using control structures, what should you be aware of?
That each If and Else If in a block is tested sequentially
What happens if a later condition is also True in an If/Else/End If structure?
It will never be considered
How many End If statements are required for an If…Then…Else statement?
The same number as the number of If-Then used
Study Notes
Course Requirements
- The collaborative learning exercise and laboratory report must be submitted on or before the specified date.
- Timeliness accounts for 10% of the total grade.
Course Materials
- Required readings: Visual Basic and Access by Jemma Development Group, Visual Basic Programming Essentials by iBook Development Group, and online resources.
Conditional Statements
- Conditional statements analyze and choose the direction of a program's flow based on certain parameters or conditions.
- Relational and logical operators are used in conditional statements, resulting in true or false outcomes.
- Examples of conditional statements:
- If condition Then statements
- If condition Then statements End If
- If condition Then statements Else statements End If
If…Then…Else…End If Decision Statement
- The If…Then…Else…End If selection structure allows the programmer to specify different actions for true and false conditions.
- Syntax: If condition Then statements Else statements End If.
- Example: If Balance – Check < 0 Then ... Else Balance = Balance – Check End If.
Nested If…Then…Else…End If Selection Structure
- Nested If structures test for multiple cases by placing If…Then…Else structures inside If…Then…Else structures.
- It's essential to consider all viable possibilities in the If/Else/End If structure.
Sample Program
- Create a temperature conversion application with multiple options and input fields, using key trapping to limit data input.
