Here are the answers to the objective questions: 5) From the list below, which is an INVALID variable name? A) @4me Variable names typically cannot start with special characters like @. They usually start with a letter or an underscore. 6) The following statement sets the value of total to -3. total -= 3; B) False The statement total -= 3; is shorthand for total = total - 3;. This means it subtracts 3 from the current value of total. It only sets total to -3 if total was initially 0. It does not always set total to -3. 7) If a new value is stored in a variable, it replaces whatever value was previously there. A) True This is a fundamental concept of variable assignment in programming. When a new value is assigned to a variable, the old value is overwritten. 8) What is one purpose of the debugger? B) It allows you to track variable values. A debugger is a tool that helps programmers find and fix errors by allowing them to execute code step-by-step and inspect the values of variables at different points during execution. 9) Most modern computers can understand and execute pseudocode B) False Pseudocode is an informal, high-level description of an algorithm intended for human understanding, not for direct execution by a computer. Computers execute machine code or compiled/interpreted programming languages. 10) Pseudocode normally does not include: A) Declarations While pseudocode might imply variable existence, it typically does not include formal, syntax-specific declarations (like specifying data types explicitly) as programming languages do. Its focus is on the logic of the algorithm. 11) What are two requirements for declaring a variable? B) Data type and variable name. To declare a variable, you need a unique name to identify it and a data type to specify what kind of data it will hold (e.g., integer, string, boolean). An initial value is often optional during declaration. 12) Why are break statements needed inside a switch's case statements? A) The break statements cause the program to jump out of the switch. break statements are used in switch statements to terminate the switch block after a matching case is executed, preventing "fall-through" to subsequent case blocks. 13) What keywords are used to construct a switch statement? D) switch, case, break, default These are the standard keywords used to define and control the flow within a switch statement. 14) What is the difference between an if statement and a switch statement? A) The if statement allows for complicated condition checking, the switch does not. if statements can evaluate complex boolean expressions involving multiple conditions and logical operators. switch statements are typically used to compare a single variable or expression against a series of discrete, constant values. 3 done, 2 left today.
