Program transformation

Program transformation is like taking a toy and changing it to make it better or different. Just like how you can take a toy car and turn it into a toy truck, you can take a program and change it to make it work better or do something different.

Programs are written in a language that computers understand, and program transformation involves changing the code of the program to make it do different things. The changes can be small, like fixing a bug, or big, like adding a new feature.

Just like how it's important to follow instructions to build a toy correctly, it's important to follow programming rules when transforming a program. This makes sure that the program still works correctly and doesn't break.

Program transformation is helpful because it allows programmers to improve their code and make it more efficient without having to start from scratch. It's like making a toy better without having to buy a new one!
