Study Notes
Arithmetic Operators
- Small Basic uses the following arithmetic operators:
-
+(addition) -
-(subtraction) -
*(multiplication) -
/(division) -
\(integer divison) -
^(power) -
Math.Remainder()(modulo)
-
Variable Naming
- The rules for naming variables in Small Basic are:
- Must start with a letter
- Can contain letters, numbers, and the underscore character (
_) - Cannot be a reserved word
Variables
- Small Basic has two types of variables:
- Local: Variables declared inside a function. Their scope is limited to that function.
- Global: Variables declared outside a function. Their scope is global, meaning they can be accessed by any function in the program.
Comments in Small Basic
- Comments are used to provide explanations and documentation within a program.
- They are ignored by the interpreter.
- Use single quotes
'at the start of a comment.
Write() vs WriteLine() Methods
-
WriteLine()prints the text and then moves the cursor to the next line. -
Write()prints the text on the same line.
Conditional Statements - If-Then, If-Then-Else, If-Then-ElseIf
-
If- Then: Executes a block of code only if a condition is true. -
If-Then-Else: Executes one block of code if a condition is true and another block if the condition is false. -
If-Then-ElseIf: Allows us to evaluate multiple conditions in sequence.
Example Coding
-
Operator Usage:
-
>=(greater than or equal to) -
*(multiplication) -
+(addition) -
>(greater than) -
AND(logical AND) -
=(assignment operator)
-
