When was Common Lisp invented?
about 1960
LISP, in full list processing, a computer programming language developed about 1960 by John McCarthy at the Massachusetts Institute of Technology (MIT). LISP was founded on the mathematical theory of recursive functions (in which a function appears in its own definition).
Which was the first compiler?
In 1951, Grace Hopper wrote the first compiler, A-0 (www.byte.com). A compiler is a program that turns the language’s statements into 0’s and 1’s for the computer to understand. This lead to faster programming, as the programmer no longer had to do the work by hand.
What was the first compiled language?
Autocode
Autocode appeared in 1952 and, as the first compiled programming language, it could be translated directly into machine code through a program called a compiler.
Is Python a Lisp?
Basically, Python can be seen as a dialect of Lisp with “traditional” syntax …
How compilers are written?
A very simple compiler can be written from an assembler and machine code. Once you have a software that is able to translate something into binary instructions, you can use the original compiler to write a more sophisticated one (then use a second further refined one to write a third and so on).
Why is Lisp called Lisp?
The name LISP derives from “LISt Processor”. Linked lists are one of Lisp’s major data structures, and Lisp source code is made of lists. The interchangeability of code and data gives Lisp its instantly recognizable syntax. All program code is written as s-expressions, or parenthesized lists.
When was the first program compiled in Lisp?
Lisp could now interprete Lisp s-expression statements used to describe data and run Lisp programs. In 1962, the first software to compile Lisp into code mixed evaluated code (processed when the code ran) and compiled code (processed before the code ran).
What does the compiler look like in Lisp?
The compiler runs in several stages: producing a (LISP) list of assembly instructions, a two-pass assembly of this list to binary code, and then binding the name in the system so it calls the machine-language code rather than the original S-expression. The assembly code list looks like:
Who was the first person to write a compiler?
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.
Why did John McCarthy create the programming language Lisp?
In the mid to late 1950s, John McCarthy at Massachusetts Institute of Technology (MIT) had a problem to solve. As part of an artificial intelligence project, he needed a programming language that could process lists of data. Sentences structured in a formal way would represent information about the world.
