내 코드에서 첫 번째 예외가 발생했습니다.

Question

수업 중에 아이스 스케이트 프로그램을 만들고 있는데 런타임 중에 오류 메시지가 표시됩니다. 컴파일러가 Judge 함수에서 성능 및 기술 점수를 추가하려고 할 때 발생합니다. 도움이 필요하시면 언제든지 알려 주시기 바랍니다.

편집 : 오류 메시지는 "가 0xc0000005 :. 액세스 위반 위치 0xCDCDCDD5를 읽고 최초의 기회 IceSkating1.exe에서 0x00FE4686에서 예외"입니다 및 "0x00FE4686 IceSkating1.exe에서 처리되지 않은 예외 : 0xC0000005 : 액세스 위반 읽기 위치 0xCDCDCDD5."

Answer 1

당신은 크기 qnty 배열 할당 :

judges = new Judge[qnty]; 

을 다음 qnty 번째 요소에 액세스하려고 : 이것은 undefined behaviour (요소가로 번호가 매겨져있다

judges[qnty].SetPerformance(p); 
    judges[qnty].SetTechnical(t); 

을 0 ~ qnty-1).

judges[count]이라고 쓰시겠습니까?

Answer 2

잘못된 판사의 점수가 업데이트되었습니다. ....

judges[count].SetPerformance(p);
