C.
C was originally developed at Bell Labs by Dennis Ritchie between 1972 and 1973 to construct utilities running on Unix.
The original C compiler was written in PDP-7 assembly language, as was Unix at the time; the port to the PDP-11 was also in assembly language..
It was the world's first self-compiling compiler – the compiler was first coded in simplified form in assembly language (the bootstrap), then re-written in its own language and compiled by the bootstrap, and finally re-compiled by itself, making the bootstrap obsolete..
History.
C was created by Dennis Ritchie at Bell Labs in the early 1970s as an augmented version of Ken Thompson's B.
Another Bell Labs employee, Brian Kernighan, had written the first C tutorial, and he pers귭 Ritchie to coauthor a book on the language..
The original version was created by John G.
Kemeny and Thomas E.
Kurtz at Dartmouth College in 1963.
They wanted to enable students in non-scientific fields to use computers..
The first C compiler, written by Dennis Ritchie, used a recursive descent parser, incorporated specific knowledge about the PDP-11, and relied on an optional machine-specific optimizer to improve the assembly language code it generated..

The first Autocode and compiler in the modern sense were developed by Alick Glennie in 1952 at the University of Manchester for the Mark 1 computer.
The FORTRAN team led by John W.
Backus at IBM introduced the first commercially available compiler, in 1957, which took 18 person-years to create..
The purpose of a compiler is to ensure that the programmer's intentions are correctly translated into a form that the computer can understand.
Code written in a high-level programming language, such as Python or Java, must first be converted into machine language before it can be run on a computer..
compilers/assemblers are themselves software, and reside wherever they were installed on the computer..

The first compiler was written by Grace Hopper in 1952 while the Lisp interpreter was written in 1958 by John McCarthy's student Steve Russell.
Writing a compiler seems like a much harder problem than an interpreter..
The achievements of Admiral Grace Murray Hopper, which include, most notably, the invention of the compiler, cemented her place at the forefront of the computing revolution that began in the early 1940s..
A number of very sophisticated features of programming languages remain out of reach for a majority of programmers.
Compilers provide you with the theoretical and practical knowledge that is needed to implement a programming language..
Early computers were meant to be used only for calculations.
Simple manual instruments like the abacus have aided people in doing calculations since ancient times.
Early in the Industrial Revolution, some mechanical devices were built to automate long, tedious tasks, such as guiding patterns for looms..
Some early milestones in the development of compiler technology:
