Debug/ error LNK2005: already defined function

헤더파일에 작성한 문법에 이상이 없는 함수 코드가 빌드되지 않고 error LNK2005 가 발생할 때는,

static 이나 inline 함수로 선언한다.

 

Some possible solutions are:

1. Declare the functions as static, which implies internal linkage
2. Inline the functions
3. Move the implementation out of the header and into a c/c++ file
