Introduction to C Programming Language Fundamentals

Understanding C Language Syntax and Structure

 C is a procedural programming language

 Programs are a collection of functions

 Follows a strict syntax and structure

Variables and Data Types in C Programming

 Used to store data

 Basic data types:

 int: integer numbers

 float: decimal numbers

 char: single characters

 bool: boolean values

Functions and Modules in C Language

 Reusable blocks of code

 Perform specific tasks

 Must be called by name

Advantages and Disadvantages of C Programming Language

 Advantages:

 Efficient and fast

 Low-level access to memory

 Widely used in system programming

 Disadvantages:

 Limited built-in functionality

 No object-oriented programming

 Steeper learning curve

Setting Up and Installing Dev C++ IDE for C Programming

1. Go to http://www.bloodshed.net/dev/devcpp.html

2. Download the latest version of Dev-C++

3. Run the installer and follow the instructions

Creating and Running First C Program Using Dev C++ IDE

1. Open Dev-C++

, 2. Create a new source file (File > New > Source File)

3. Write the "Hello, World!" program:

#include <stdio.h>



int main() {

printf("Hello, World!\n");

return 0;

}

4. Save the file with a .c extension

5. Click the hammer icon to compile

6. Click the green arrow to run

nderstanding C Language Syntax and Structure

C Language Syntax

 C is a procedural language, which means it follows a step-by-step approach to break down a
task.

 C programs are composed of functions which are blocks of code that perform specific tasks.

 Each C program has a main function, which serves as the entry point for the program's
execution.

 C uses curly braces {} to define the beginning and end of a block of code.

 Statements in C are ended with a semicolon ;

C Language Structure

 C code is organized into headers and source files.

 Headers contain declarations for functions and variables, while source files contain the
definitions of these functions and variables.

 C code is compiled and linked using a compiler and a linker.

 C code is typically written in a text editor and then compiled and linked using a build tool
such as make.

Key Terms

 Procedural: a programming paradigm that uses step-by-step procedures to break down a
task

 Function: a block of code that performs a specific task

 Main function: the entry point for a C program

 Curly braces {}: used to define a block of code in C
