To show changes between commits in Git, you can use the git diff command. Here are a few common usages:
1. Show changes between the working directory and the last commit:
   git diff
2. Show changes between the last commit and the staging area:
   git diff --cached
3. Show changes between two specific commits:
   git diff <commit1> <commit2>
   Replace <commit1> and <commit2> with the respective commit hashes or references (e.g., branch names).
4. Show changes between a commit and its parent:
   git diff <commit>
   This will show the changes introduced by that particular commit.
You can also use git log -p to see the commit history along with the differences introduced in each commit.
