Answer
Data types define what kind of data a variable can hold.
Choosing the correct data type helps avoid errors and manage memory efficiently. For instance, using `int` for a product quantity ensures you can't assign a non-integer value. If you mistakenly declare `double quantity = 5;`, it might lead to logic errors in your e-commerce calculations.
