기본적인 C언어란 프로그래밍 언어이다.

컴퓨터와의 대화에 사용하기 위해 일종의 의사소통이다.

ex) 한국인 영어> 통역사(컴퓨터 본체) > 일본인
ex) > 한국말 영어> 통역사 > 일본말 > 일본인
이런식으로 가능한 조건이 C언어이다.
하지만 컴퓨터에서는 의사소통이 불가능이므로  C언어로 의사소통 할수있다.
ex) 한국어 C언어 > 컴파일러(C언어 기계어) > 컴퓨터
*컴파일러이란? > 프로그래밍 언어로 작성한 프로그램을 컴퓨터가 이해할 수 있도록 기계어로 번역하는역할을합니다. (Compile)
*기계어란? 컴퓨터가 이해할 수 있도록 0과1로 구성된 언어체계입니다.
