How do I choose the right data type in programming?

Choosing the right data type depends on the kind of data you need to store and how you plan to use it. For example, if you need to store whole numbers, you might choose an integer type. If you need to store decimal numbers, a float or double might be more appropriate.

What are the common data types I should know?

Common data types include integers, floats, strings, booleans, and arrays. Each serves different purposes based on the data you are handling.

Can you give me an example of when to use a list versus a dictionary?

Sure! Use a list when you need an ordered collection of items, like a list of names. Use a dictionary when you need to associate keys with values, like storing a person's name with their age.

What happens if I choose the wrong data type?

Choosing the wrong data type can lead to errors, inefficient memory usage, and unexpected behavior in your program. It's important to understand the characteristics of each type.
