This reads like something off of a homework assignment, but whatever.

Quality code is everything. If your program crashes every time you run it, or is functionally unable to do what it is supposed to do, you lose users, and as a result, money.

Stability and robustness go hand in hand. Programs which account for every possible case (robustness) are less likely to throw exceptions, and crash.

Yeah it is a homework assignment, but thank you for giving me an outline of the importance of coding. Very helpful

This pretty much sums it up quite well. I'd also mention that internal commentary makes your code easier to read and understand by another program, as the majority of the time in the workplace. The person maintaining your code a few months down the line, won't be you and it could be the first time they've ever seen it. Internal commentary helps a lot. A-Level computing.
