C Programming Tutorial: A Comprehensive Guide for Beginners78

C programming is a general-purpose, procedural language that has been widely used for developing operating systems, embedded systems, and a variety of applications. Its popularity stems from its efficiency, portability, and low-level access to hardware.

Getting Started

To begin learning C programming, you will need a few essential tools:* A text editor or an integrated development environment (IDE)
* A C compiler
* Basic knowledge of computer programming concepts

Hello World!

A traditional starting point for any programming language is the "Hello World!" program. This program prints the message "Hello World!" on the console.
#include
int main() {
printf("Hello World!");
return 0;
}

This program includes the stdio.h header file, which is necessary for input and output operations. The main function is the entry point of the program, and it contains a call to the printf function with the string "Hello World!" as its argument. The at the end of the string indicates a newline character.

Data Types and Variables

C programming uses various data types to store different types of data. Some of the common data types include:* int: integer (whole number)
* float: floating-point number
* char: character
* double: double-precision floating-point number

Variables are used to store data in your program. They are declared with a data type and a name.
int age;
float salary;
char gender;
double area;

Operators and Expressions

Operators are special symbols that perform operations on variables or constants. C programming uses various operators, including:* Arithmetic operators: +, -, *, /, %
