How Programming Languages Evolved: From FORTRAN to Python

<h1>How <a href="/blog/functions-in-programming">Programming</a> Languages Evolved: From FORTRAN to Python</h1>

<p>The story of programming languages is a fascinating journey through the <a href="/blog/the-history-of-cryptocurrency-from-bitcoin-to-now">history</a> of computing, innovation, and human creativity. From the early days of machine code to the sophisticated languages we use today, programming languages have evolved dramatically to meet the changing needs of developers and industries. In this comprehensive article, we will explore the <strong>programming languages evolution FORTRAN Python</strong> — tracing the path from one of the very first high-level languages, FORTRAN, to the versatile and popular Python. Along the way, we will dive into the historical context, key features, and practical examples that illustrate how programming languages have transformed over the decades.</p>

<h2>The Dawn of Programming Languages: Enter FORTRAN</h2>

<p>Before the invention of high-level programming languages, computers were programmed using machine code — a tedious and error-prone process involving binary instructions. The need for a more human-readable way to write programs led to the creation of the first high-level languages, among which FORTRAN (Formula Translation) holds a special place.</p>

<h3>What is FORTRAN?</h3>

<p>Developed in the 1950s by IBM and led by John Backus, <strong>FORTRAN</strong> was the first widely used high-level programming language specifically designed for scientific and engineering calculations. Released in 1957, FORTRAN allowed programmers to write code using mathematical formulas and common algebraic notation instead of complicated machine instructions.</p>

<ul>
<li><strong>Purpose:</strong> Scientific and numerical computing</li>
<li><strong>Key Features:</strong> Strong support for mathematical expressions, arrays, and <a href="/blog/loops-and-conditionals">loops</a></li>
<li><strong>Legacy:</strong> Still in use today for high-performance computing and legacy systems</li>
</ul>

<h3>Practical Example in FORTRAN</h3>

<p>Here is a simple example of a FORTRAN program that calculates the factorial of a number:</p>

<pre>
PROGRAM FACTORIAL
INTEGER N, I
INTEGER FACT
PRINT *, 'Enter a positive integer:'
READ *, N
FACT = 1
DO 10 I = 1, N
FACT = FACT * I
10 CONTINUE
PRINT *, 'Factorial of ', N, ' is ', FACT
END
</pre>

<p>This example demonstrates the ease with which mathematical operations could be expressed, compared to earlier machine code.</p>

<h2>The Evolution Continues: From Assembly to Structured Languages</h2>

<p>Following FORTRAN, several other languages were developed to improve readability, maintainability, and functionality. Among these were COBOL, ALGOL, and later, C, each marking important milestones in the evolution of programming languages.</p>

<h3>COBOL: Programming for Business</h3>

<p>While FORTRAN targeted scientific computing, <strong>COBOL</strong> (Common Business-Oriented Language), introduced in 1959, was designed for business applications. Its syntax resembled English prose, making it more accessible to non-technical users.</p>

<h3>ALGOL and the Birth of Structured Programming</h3>

<p><strong>ALGOL</strong> (Algorithmic Language), developed in the late 1950s and early 1960s, introduced the concept of structured programming — organizing code into blocks, procedures, and control structures like loops and conditionals. ALGOL influenced many later languages, including Pascal, C, and Java.</p>

<h3>C Language: Low-Level Power with High-Level Ease</h3>

<p>Created in the early 1970s by Dennis Ritchie at Bell Labs, the <strong>C language</strong> combined the efficiency of low-level programming with the advantages of high-level language features. C's portability and powerful features made it ideal for system programming, including operating system development.</p>

<h3>Example: Hello <a href="/blog/how-satellites-changed-world-sputnik-starlink">World</a> in C</h3>

<pre>
#include &lt;stdio.h&gt;

int main() {
printf("Hello, World!\n");
return 0;
}
</pre>

<h2>The Rise of Object-Oriented Programming: C++ and Beyond</h2>

<p>As software projects grew in size and complexity, programmers sought ways to better organize code and promote reuse. This led to the rise of <em>object-oriented programming</em> (OOP), which models software as a collection of interacting objects.</p>

<h3>C++: Extending C with Objects</h3>

<p>In the early 1980s, Bjarne Stroustrup developed <strong>C++</strong> by adding OOP features to C. C++ combined the power and efficiency of C with classes, inheritance, and polymorphism, enabling developers to build complex software systems.</p>

<h3>Practical Example: Class in C++</h3>

<pre>
#include &lt;iostream&gt;
using namespace std;

class Rectangle {
public:
int width, height;
int area() {
return width * height;
}
};

int main() {
Rectangle rect;
rect.width = 5;
rect.height = 10;
cout &lt;&lt; "Area: " &lt;&lt; rect.area() &lt;&lt; endl;
return 0;
}
</pre>

<h2>The Web and Scripting Languages: JavaScript, Perl, and PHP</h2>

<p>The expansion of the internet in the 1990s created new demands for languages that could handle web development and scripting tasks efficiently. This period saw the rise of languages like JavaScript, Perl, and PHP.</p>

<ul>
<li><strong>JavaScript:</strong> Developed by Brendan Eich in 1995, JavaScript became the language of the web, enabling interactive web pages and client-side scripting.</li>
<li><strong>Perl:</strong> Known as the "Swiss Army knife" of scripting languages, Perl was widely used for text processing, system administration, and web development.</li>
<li><strong>PHP:</strong> Created in 1994 by Rasmus Lerdorf, PHP is a server-side scripting language that powers a significant portion of the web.</li>
</ul>

<h2>Modern Programming Languages: The Rise of Python</h2>

<p>In the late 1980s, Guido van Rossum began developing a new language that would emphasize readability, simplicity, and versatility. This language, <strong>Python</strong>, was officially released in 1991 and has since become one of the most popular programming languages worldwide.</p>

<h3>Why Python Became Popular</h3>

<ul>
<li><strong>Readability:</strong> Python's clean syntax and indentation-based structure make code easy to read and write.</li>
<li><strong>Versatility:</strong> Used in web development, data science, machine learning, automation, and more.</li>
<li><strong>Large Standard Library:</strong> Comes with built-in modules for diverse tasks.</li>
<li><strong>Strong Community:</strong> Extensive third-party libraries and frameworks.</li>
</ul>

<h3>Python Syntax Example: Factorial Function</h3>

<pre>
def factorial(n):
if n == 0:
return 1
else:
return n * factorial(n - 1)

num = int(input("Enter a positive integer: "))
print(f"Factorial of {num} is {factorial(num)}")
</pre>

<p>This example highlights Python's simplicity compared to the earlier FORTRAN example while performing the same task.</p>
