Question

What is pair programming?

Baibhav Kumar · Answer

Pair programming is a software development technique where two developers work together at the same workstation to write code. One developer takes the role of the "Driver", who writes the code, while the other is the "Navigator", who reviews each line of code as it is written and thinks strategically about the direction of the work. The roles are usually switched at regular intervals to keep both developers engaged and to share knowledge effectively. Benefits: Helps reduce bugs through real-time review Encourages knowledge sharing between team members Improves team collaboration and communication

What is Pair Programming? Pair programming is a software development technique where two developers work together at one computer to write code. One person types (called the Driver ) while the other reviews and guides (called the Navigator ). It’s a core practice in Agile and Extreme Programming (XP) methodologies because it improves code quality , knowledge sharing , and team collaboration . Roles in Pair Programming Driver: Writes the code. Focuses on the syntax, logic, and immediate task. Navigator: Reviews the code as it’s written. Thinks about design, possible bugs, and the big picture. Suggests improvements and next steps. Example: Let’s say you’re building a function in C# to calculate factorial: Driver writes: int Factorial(int n) { if (n Navigator observes and suggests: Looks good! But what if n is negative? Let’s handle that case. Driver updates: int Factorial(int n) { if (n The result: fewer bugs, better validation, and shared understanding. Benefits of Pair Programming Improves code quality Enhances knowledge sharing Boosts team productivity Reduces defects Strengthens communication and collaboration Challenges Can be time-consuming Slightly higher short-term cost (two devs per task) Requires good coordination and communication In Short: Pair programming = Two minds, one keyboard. It helps teams write better code faster through real-time collaboration.
