C Language Tutorial: A Comprehensive Beginner‘s Guide179

Welcome to the world of C programming! C is a powerful, general-purpose programming language that has been used to develop countless applications, from operating systems to embedded systems. In this tutorial, we will delve into the fundamentals of C programming, allowing you to build a strong foundation for your coding journey.

Introduction to C

C is a structured programming language developed by Dennis Ritchie at Bell Labs in the early 1970s. It is a versatile language that combines the power of low-level system programming with the convenience of high-level languages. C forms the basis of many modern operating systems, including Linux, macOS, and Windows.

Data Types in C

Before we dive into programming, let's understand the different data types available in C. Data types define the type of data a variable can hold, such as integers, floating-point numbers, or characters. The main data types in C include:* Integers: Whole numbers, both positive and negative (e.g., int, long)
* Floating-point numbers: Numbers with decimal points (e.g., float, double)
* Characters: Single characters (e.g., char)
* Strings: Arrays of characters (e.g., char[])
* Arrays: Collections of elements of the same data type (e.g., int[])

Variables and Constants

Variables are used to store data in your program. You declare a variable by specifying its data type and name. Constants, on the other hand, represent fixed values that cannot be changed during the program's execution.
int age = 25; // Variable
const float PI = 3.14; // Constant

Operators

Operators are symbols that perform operations on variables or values. C provides a wide range of operators, including arithmetic operators (+, -, *, /), relational operators (==, !=, >,
