    • Context help
    • Syntax highlighter
    • Auto indent

  5. Which IDE component turns high-level source code into a form that can be executed?

    • Editor
    • Trace table
    • Structure diagram
    • Translator

  6. Which tool inside an IDE allows a programmer to set a breakpoint to pause program execution?

    • Compiler
    • Debugger
    • Interpreter
    • Editor

  7. Which type of error occurs when a program runs without crashing but gives a wrong result because the algorithm is flawed?

    • Breakpoint
    • Error diagnostics
