C Data Types You Need to Know: An Introduction

Article Summary

C data types are classifications that tell the compiler exactly what kind of value a variable holds — from whole numbers (`int`) to text (`char`), decimals (`float`), and precise values (`double`). This article covers basic, derived, enumerated, and void C data types. You'll gain the foundational knowledge needed to write valid, error-free C code.

Before you start programming in C, you will need to learn the basics of C data types. In many ways, programming simply involves using logic to record, access, and manipulate data. But not all data is made equal.

Consider that you have “words,” and you have “numbers” in grammar — programming works much like this, but the distinctions between data types are much more specific and much clearer. If you want to write in the appropriate c syntax, you must first understand all these data types.

Why are data types important in C?

C is a strictly typed language. What does this mean? In some other languages, such as PHP, you simply declare a variable, and the program itself determines what type of variable it is. But in C, not only do you need to tell the program what type of variable you’re declaring, but you need to adhere to that. For instance, you cannot tell C that something is a number and then later change it to a string. Types are defined upon creation.
