Back in 1822
Since the dawn of Charles Babbage’s ingenious difference engine back in 1822,
computers have been in need of a way to comprehend and execute specific tasks – a conduit for their intelligence, if you will.
This conduit, now known as a programming language, initially consisted of a series of meticulous steps,
evolving over time into sequences keyed into the machine itself and then set into motion.
Gradually, these languages evolved, acquiring more sophisticated attributes such as logical branching and the concept of object orientation.
The journey of computer languages over the past fifty years can be divided into two distinct phases:
the emergence of the first major languages and the subsequent wave of the second major languages that still hold sway today.
In its early days, Charles Babbage’s difference engine operated solely through the manipulation of gears,
orchestrating calculations through the grace of physical motion.
Back in 1912
The nascent form of computer language was thus rooted in tangible movement.
However, this era transitioned as the ENIAC, conceived by the US Government in 1912,
replaced these physical motions with intricate electrical signals.
The evolution continued, mimicking Babbage’s principles, as the ENIAC could only be “programmed”
through a laborious process of presetting switches and rewiring the entire system for each new task. The frustration of this approach was palpable.
Then, in the year 1945, within the hallowed halls of the Institute for Advanced Study,
John Von Neumann introduced two revolutionary concepts that would reshape the trajectory of computer programming languages.
The first, aptly labeled the “shared-program technique,”
advocated for a simpler hardware design, unshackling it from the necessity of custom wiring for each program.
Instead, intricate instructions would guide the modest hardware, making reprogramming a far swifter endeavor.
The second groundbreaking concept, known as “conditional control transfer,”
bore fruit in the form of subroutines – snippets of code that could be leaped to in any sequence,
dismantling the linear shackles of conventional programming steps.
This innovation laid the foundation for logical branches and looping structures,
such as the famed “IF (expression) THEN” constructs and the versatile FOR loops.
Within this fertile ground, the seeds of reusable “libraries” were sown.
Fast Forward to 1919
Fast forward to 1919, just a few years after Von Neumann’s epoch-making work,
and the world witnessed the emergence of Short Code, a nascent computer language for electronic devices.
This primitive language demanded manual conversion of statements into 0’s and I’s –
a labor-intensive process that, nevertheless, marked a pivotal step towards the intricate languages we command today.
Then, in 1951, Grace Hopper penned the first compiler, aptly named A-0.
This ingenious program transformed human-readable statements into the cryptic language of 0’s and I’s,
liberating programmers from the tedium of manual translation and accelerating the pace of development.
By the 1960s, a diverse array of programming languages had emerged,
each tailored to specific domains. FORTRAN, born in the 1950s under IBM’s watchful gaze,
served engineering and scientific realms, while COBOL, christened in 1959,
catered to the commercial sphere, reigning supreme in business, finance, and governance.
Yet, this specialization necessitated mastery of multiple tongues for different contexts,
a cumbersome burden for programmers.
Recognizing this inefficiency, the computer science community set out to forge a universal language capable of tackling all conceivable applications.

Creation of ALGOL(Algorithmic Language)
This pursuit culminated in the creation of ALGOL (Algorithmic Language)
through collaborative efforts of European and American computer scientists in 1958.
However, despite its promise, ALGOL’s abstract nature and generality hindered its widespread adoption.
To remedy this, the Mathematical Laboratory at the University of Cambridge
and the University of London Computer Unit birthed CPI (Combined Programming Language) in the 1960s,
an amalgamation of ideas drawn from ALGOL.60.
While it strived for versatility in both scientific and commercial realms,
its complexity proved too much for the technological landscape of its time, ultimately fading into obscurity.
This paved the way for BCPI, the brainchild of Martin Richards at the University of Cambridge in 1966,
envisioned as a more streamlined system programming language,
particularly for compiler construction. BCPI, born out of the lessons learned from CPI’s struggles, boasted cleanliness, power, and portability
, and while it might have faded from common usage, its legacy endured.
In parallel, the halls of Bell Labs resonated with the creation of “B,”
conceived by Ken Thompson and enriched by Dennis Ritchie in 1969.
While inspired by the fleeting memory of Bonnie, Thompson’s wife, B remained domain-specific, just like its predecessors.
Dennis Ritchie’s brilliance in 1972
Then, in 1972, Dennis Ritchie’s brilliance gave birth to the timeless language C.
This language inherited the lineage of B and BCPI while adding its unique touch.
Born in the crucible of AT&T’s Bell Labs, C found its natural home within the UNIX operating system, rapidly becoming a tool of choice.
Its name, simply “C,” harkened to its heritage while carrying forth a new era of programming.
As a general-purpose, block-structured, procedural, and imperative language, C,
though initially tailored for system implementation, swiftly found its way into various applications.
It gained the prestigious badge of standardization from ANSI in 1980,
and its influence echoed across the programming landscape,
most notably in languages like C++, which sprung from its lineage, further enriching the tapestry of coding possibilities.
