Module 1: Foundations

History of C Programming

📚 Learning Objectives

Understand the origins of C language
Identify the creator and historical context
Recognize the influence of C on modern OS development

Dennis Ritchie (1941-2011)

The Father of C Programming

C was created in 1972 by Dennis Ritchie at Bell Labs as part of the development of the UNIX operating system. Ritchie had worked on improving the B programming language (itself a simplified version of BCPL) and sought to create a more powerful and efficient language capable of system-level performance while remaining portable across different hardware.

The success of C was immediate, leading to the rewrite of the Unix kernel in C, making it one of the first operating systems not written in assembly language.

🎥 Video Explanation

Key Takeaways:

C was born from the need to develop UNIX.
It bridged the gap between low-level and high-level languages.
Dennis Ritchie's contribution changed the software world forever.

🧠 Practical Implementation

In this section, we observe the syntax and structure of a basic C program that commemorates its history.

history.c

#include <stdio.h>

int main() {
    printf("C Language - Created by Dennis Ritchie\n");
    printf("Year: 1972\n");
    printf("Location: Bell Labs\n");
    return 0;
}

🚀 Topic Challenge

Write a program that takes two integers as input and prints their sum. Use scanf() for input and printf() for output.

Requirements:

Include <stdio.h>.
Format: %d %d for input.
Ensure the main function returns 0.
