| What are the rules for variable names? | Must be: Alphanumeric Can include underscore, can't start with one can't begin with a numeral can't include the space character can't capitalize the first letter |
| What are the arithmetic operators? | + Add - Subtract * Multiply / Divide - Floating Point // Divide - Integer % Mod - the remainder |
| What are the 3 fundamental control structures? | Sequence Selection Repetition |
| What are the 6 phases of software development? | Requirements Design Implementation (AKA 'coding') Testing Deployment Maintenance |
| What are the 3 Important Aspects of computer learning? | Knowledge Understanding Ability |
| What does the colon do at the end of a for-statement? (less likely to appear) | It's a signal to the interpreter that subordinate statements will follow. |
| What are the 3 Kinds of Errors? | Syntax Errors Execution Errors Logic Errors |
| What are the 4 steps of the while-loop Checklist? | 1. Choose a variable to control the loop 2. Initialize that variable before the loop 3. Use that variable in the (Boolean) statement of the while-loop 4. Alter the value of the variable in the loop so that eventually the expression becomes false. |
| What can we not change in strings? (less likely to appear) | The characters. We can only replace the strings, and/or 'slice' them. |
