What is the Data Type
In programming, data types are the classification or categorization of data values. There are four main data types in most programming languages:
-Integer: A whole number, positive or negative (e.g. 1, -5, 100)
-Float: A decimal number (e.g. 3.14, -2.5)
-String: A sequence of characters (e.g. “hello”, “world”)
-Boolean: True or false values (e.g. true, false)
Data types are important because they can affect the way a program operates on them and how they are stored in memory. For example, an integer takes up less space in memory than a float, so it may be more efficient to use an integer when storing large numbers. However, a float is necessary for storing decimal values such as 3.14 or -2.5.
