Which of the following is an example of a data type?

An integer is a specific type of data that represents whole numbers, which can be positive, negative, or zero. It is one of the most fundamental data types in programming, used to perform arithmetic operations and control the flow of programs via conditions. Understanding integers is crucial for working with numerical data in coding, as they form the basis for more complex operations and data manipulations.

Function, loop, and array are not data types in the same sense. A function refers to a block of code designed to perform a specific task and can return a value, but it itself does not represent a type of data. A loop is a control structure that allows code to be executed repeatedly based on a condition, not a data type. An array is a collection of items stored at contiguous memory locations, which can hold multiple values of the same data type, but it is not a base data type like an integer. Each of these concepts plays a significant role in programming, yet only the integer represents a fundamental type of data used in many programming languages.
