Tools in Program Development

Question 1

What is an Editor in program development?

Answer 1

A software where the source code is written in a high-level language. Examples include Integrated Development Environments (IDEs) like Visual Studio or Eclipse.

Question 2

What is a Translator in program development?

Answer 2

A tool that converts high-level language into machine code. There are two main types:

• Compilers: Translate the entire code at once
• Interpreters: Translate code line-by-line during execution

Question 3

What is a Debugger in program development?

Answer 3

A tool for testing the program and detecting errors. It allows developers to:

* Step through code execution
* Set breakpoints
* Inspect variable values
* Track the program flow

Question 4

What features does an Integrated Development Environment (IDE) typically include?

Answer 4

• Pretty Print: Formats code for readability
• Automatic Indentation: Adjusts indentation to reflect logical structure
• Syntax Checking: Identifies syntax errors as code is written
• Highlights Undeclared Variables: Alerts when code refers to undefined variables
• Type Checking: Ensures values assigned to variables are compatible with their declared types

Question 6

What are the tools used for finding errors in code?

Answer 6

• Dry Run/Trace Table: Manually stepping through code logic on paper
• Breakpoint: Halting execution at a specific point to examine the current state
• Variable Watch: Monitoring variable values during execution
• Stepping: Moving through code one line at a time, observing execution flow
