2.5 programming languages

• What is an IDE?

  A software package for writing code
• What feature allows code to be written and edited in an IDE?

  Editor
• What is a feature of the code editor in an IDE?

  Automatic line numbering
• What does colour coding in an IDE help with?

  It helps differentiate code elements
• What is the purpose of auto-correct in an IDE?

  To fix common coding errors automatically
• What does auto-suggestion do in an IDE?

  It suggests code completions as you type
• What is the function of a runtime environment in an IDE?

  It allows code to run on different platforms
• How does a runtime environment benefit programming?

  It enables coding for hardware without access
• What is the role of error diagnostics in an IDE?

  To locate and fix coding errors
• What do breakpoints allow a programmer to do?

  Pause the program to examine code
• What does variable tracing show during program execution?

  The changing values of variables
• What is syntax highlighting used for in an IDE?

  To show where syntax errors occur
• What is the purpose of translators in programming?

  To translate code into executable format
• What do compilers do in programming?

  Translate the whole code into machine code
• When are compilers typically used in development?

  At the end when code is finished
• What do interpreters do in programming?

  Translate and execute source code line by line
• What happens if code is incorrect when using an interpreter?

  Interpreting is stopped
• What is a characteristic of high-level programming languages?

  They use English-like keywords
• What is an example of a high-level programming language?

  Java
• What is a disadvantage of compiled programs?

  Code must be re-compiled after changes
• What is a benefit of compiled programs?

  They run quickly without additional software
• What is a characteristic of 4th generation programming languages?

  They detail what computation to perform
• What is an example of a 4th generation language?

  SQL
• What is a disadvantage of using interpreters?

  Execution is slower due to translation
• What is an advantage of using interpreters?

  Errors can be quickly spotted
• What happens to instructions in an interpreter?

  They are executed as soon as translated
• What is a limitation of code compiled on one platform?

  It will not run on another platform
• What is the relationship between high-level languages and machine code?

  One instruction translates into many machine code instructions
• What is the purpose of SQL in 4th generation languages?

  To perform database queries
• What is a key feature of declarative languages?

  They specify what to compute, not how
• What is a common use for assembly code?

  Programming device drivers
• What is the main function of a debugger?

  To help locate and fix errors
• What is the relationship between machine code and assembly code?

  One assembly instruction translates to one machine instruction
• What is the main advantage of using a compiler over an interpreter?

  Compiled programs run faster
• What is a disadvantage of high-level languages?

  They require translation to machine code
• What is the main purpose of a programming language?

  To communicate instructions to a computer
• What is the significance of using mnemonics in assembly code?

  They make code easier to understand
• What is the role of keywords in high-level programming languages?

  They define the structure and commands
• What is the main challenge of using machine code?

  It is difficult for humans to understand
• What is the purpose of object code generated by compilers?

  To be executed by the computer
