Code analysis is like checking answers on a test. When you finish a test, you go back and check your answers to make sure they are correct. Code analysis is like checking the answers in a program.
When someone writes a program, they need to make sure it works correctly. Code analysis helps them do this by looking at the program's code (kind of like the instructions for the program) and checking it for mistakes. Just like how you check your answers on a test for mistakes.
Code analysis can also help find other problems with a program, like security issues or performance problems. It's a little bit like checking if your toy is safe to play with, or if it moves too slow or too fast.
So, code analysis is like checking a program to make sure it works properly, is safe, and performs well, just like checking your answers on a test or checking your toys before playing with them.
