Add trial test to demonstrate increment operators

This commit adds a trial test to the project, which serves as an example and demonstrates the usage of increment operators. The test file includes two test cases: one checks the sum of 1 and 1, expecting the result to be 2 😊, and the other checks the product of 2 and 2, expecting the result to be 4 😄. The main focus of the commit is to showcase the difference between postfix and prefix increment operators. Additionally, code changes were made to display initial information, perform operations with increment operators, implement user input for result comparison, and provide appropriate feedback based on the user's answer. I also added dependencies for testing and updated the .gitignore file. 🎉
