GPT Task 1: A simple program to help users track their daily expenses. The program prompts the user to input the number of days they wish to track expenses, and for each day, it asks for the expense amount.

2. Open the project in Visual Studio or another C# IDE.
3. Compile and run the program.
4. Enter the number of days and then input your expenses for each day when prompted.

• Understanding arrays and how to store data for multiple days.
• Using loops to process user input.
