Who created the compiler?

Admiral Grace Murray Hopper
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. Trained as a mathematician, her career spanned six decades.

How can a compiler be compiled?

You can only use language features the compiler from the step above can compile. You use the compiler from step 1 to compile the compiler from step 2. This leaves you with an assembly that was originally written in a subset of the new language, and that is able to compile a subset of the new language.

What runs the compiler?

A compiler is a special program that processes statements written in a particular programming language and turns them into machine language or “code” that a computer’s processor uses. The programmer then runs the appropriate language compiler, specifying the name of the file that contains the source statements.

What is used to compile a compiler?

A very simple compiler can be written from an assembler and machine code. The something could be instructions written in the same programming language the compiler uses, creating new self-hosting. Gcc, one of the most popular C compilers, was built using this technique.

Who wrote first compiler?

Grace Hopper
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.

Who was the first person to write a compiler for a computing device?

By 1952, Hopper had finished her program linker (originally called a compiler), which was written for the A-0 System. During her wartime service, she co-authored three papers based on her work on the Harvard Mark 1….Grace Hopper.

What is the role of compiler?

compiler, computer software that translates (compiles) source code written in a high-level language (e.g., C++) into a set of machine-language instructions that can be understood by a digital computer’s CPU. Other compilers generate machine language directly.

Can a compiler be written in the language it compiles?

In computer science, bootstrapping is the technique for producing a self-compiling compiler — that is, a compiler (or assembler) written in the source programming language that it intends to compile.

What is the best way to write a compiler?

Typically, compiler authors go one of two routes: Write the entire compiler in some other existing language. This is generally the simplest option. Write just enough code in some other language to have a minimally usable translator, and use that “scaffolding” as a base to write the compiler proper in the language it’s intended to compile.

What is the difference between cross compiler and decompiler?

A compiler that can run on a computer whose CPU or operating system is different from the one on which the code it produces will run is called a cross-compiler. A bootstrap compiler is written in the language that it intends to compile. A program that translates from a low-level language to a higher level one is a decompiler.

What is the difference between a compiler and a program?

* There are programs to help design the hardware that interprets and executes the instructions, but that arguably sits outside the definition of a compiler. Such programs generate hardware descriptions — circuit diagrams and the like — as opposed to the directly executable files a compiler outputs.

What are the limitations of compiler design?

Resource limitations led to the need to pass through the source code more than once. A compiler for a relatively simple language written by one person might be a single, monolithic piece of software. However, as the source language grows in complexity the design may be split into a number of interdependent phases.
