Subject: [PATCH] Update calculator.c to display full calculation.

In this contribution, I added more descriptive output to the calculation results. Now, the program will display the full calculation entered by the user along with the result. This makes the program more informative and user-friendly. Additionally, I added an extra check to the '%' operator case to prevent division by zero errors.
