C++ String-> Replace가 예상대로 작동하지 않습니다.

Question

제가 소유하고있는 우주 시뮬레이션 게임에서 행성에 대한 광란의 스타일 스토리를 생성하는 프로그램을 만들려고합니다. 사용자가 스토리 템플리트의 변수를 백분율 기호 안에 넣은 .txt 파일로 스토리 템플리트를 입력 할 수 있도록 설계되었습니다. 프로그램은 .txt 파일을 읽고 스토리를 가져 와서 변수를 찾은 다음 적절한 임의 정보 (현재 정의한 두 가지 변수 만 있음)로 변수를 채 웁니다.

내가 겪고있는 문제는 코드/출력에서 ​​볼 수 있듯이 디버깅하려는 모든 시도가 컴퓨터에서 적절한 텍스트를 생성한다고해도 스토리의 변수를 대체하지 않는다는 것입니다. 변수가 텍스트에 있음을 인식합니다.

문제의 실제 줄은 "GetVar()"함수 정의의 아래쪽에 있습니다.

%SpaceRace% is a space-faring species in Star Wars, and %NonSpaceRace% is a non-space-fairing species in Star Wars. 

어떻게 보일지 출력 :

SpaceRace: 9 
Chevin

Answer 1

String.Replace은 바뀐 값으로 새 문자열을 반환하며 적절한 위치에서 대체하지 않습니다. 보다는 :

str->Replace("%SpaceRace%", var[varctr]); 

가 더 들어

str = str->Replace("%SpaceRace%", var[varctr]); 

필요 the MSDN entry for String.Replace를 참조하십시오.
