Programming Concepts Quiz

Which type of error is most likely to be caused by incorrect input from the user?

• Logic Error

• Runtime Error

• Compile Error

• Syntax Error

What is the primary benefit of using constants in programming?

• Constants are faster to compute than variables.

• Constants increase the execution speed.

• Constants manage memory more efficiently.

• Constants help avoid repeating literal values and make code easier to maintain.

When might developers need to revisit a previous stage of the software development life cycle (SDLC)?

• Any time an issue prevents the software from functioning as expected

• Only if the software fails to meet initial requirements

• During deployment

• After testing

What is the main goal of the system analysis phase?

• Analyzing data flow and identifying inputs and outputs

• Writing the code

• Fixing bugs

• Designing the user interface

Which SDLC phase focuses on understanding what the software system needs to do?

• Requirements Specification

• Testing

• Implementation

• System Analysis

Which of the following is NOT a cause of syntax errors?

• Dividing a number by zero

• Missing a corresponding closing brace

• Using an undeclared variable

• Misspelling a keyword

Which of the following would NOT be classified as a runtime error?

• An operation the environment cannot execute

• Input error

• Mistyped keyword

• Division by zero

What is the primary purpose of including comments in a Java program?

• To slow down program execution

• To make the code longer and more complex

• To introduce major steps and explain difficult parts of the code

• To prevent the code from being compiled

Which debugging technique is most useful for small, simple programs?

• Hand-tracing

• Stack tracing

• Using a debugger utility

• Breakpoint insertion

Which statement about type conversion is true?
