When we say that Dennis Ritchie developed C language, do we mean that he has created a compiler (using an 'already' developed other language) which can compile the source code written in C language?if yes, what was language he used to write first C compiler? I understand a compiler is a program and we can create another compiler for C language using presently available C compiler. Is that correct?
What is the history of the C compiler?
c;compiler
From wiki:Ritchie is best known as the creator of the C programming language and a key developer of the Unix operating system, and as co-author of the definitive book on C.Also from wiki: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 C compiler was also written by him, in assembly.This page from bell-labs answers most of your questions.
