Small Basic Arithmetic and Variables Quiz

Arithmetic Operators

• Small Basic uses the following arithmetic operators: +, -, *, /, \
• The \ operator is used for integer division
• The operator * is used for multiplication
• The operator + is used for addition
• The operator / is used for division
• The operator - is used for subtraction
• The order of execution of arithmetic operators is from left to right

Variables

• Variables are used to store data in Small Basic
• Variables can be named using letters, numbers, and underscores
• Variable names must start with a letter
• There are two types of variables in Small Basic:
  • Local variables: These are defined within a specific block of code and can only be accessed within that block.
  • Global variables: These are defined outside of any block of code and can be accessed from anywhere in the program.
• The ReadNumber() method reads a numeric value from the user during program execution.

Comments

• Comments are used to explain code and are ignored by the compiler.
• Comments can be added to a program using the // symbol.

WriteLine() and Write() Methods

• The WriteLine() method displays text on a new line.
• The Write() method displays text on the same line as the previous output.

Conditional Statements

• Conditional statements allow you to control the flow of your program based on certain conditions.
• The If-Then statement executes a block of code if a condition is true.
• The If-Then-Else statement executes one block of code if a condition is true and another block of code if the condition is false.
• The If-Then-ElseIf statement allows you to check multiple conditions and execute different blocks of code based on the true condition.

Operators

• The >= operator checks if a value is greater than or equal to another value.
• The > operator checks if a value is greater than another value.

Program Example

• To count the number of students under 14 years old who bring lunchboxes from home, the following steps are followed:
  • Declare a variable to store the count of students under 14.
  • Use a loop to ask each student their age and whether they bring lunch from home.
  • If the student's age is under 14 and they bring lunch from home, increment the count variable.
  • Display the total count of students.
