저는 C++을 처음 접했을뿐입니다. 나는 올해 학습을 시작했습니다. 텍스트 문서를 가져 와서 배열에 저장하는 작은 프로그램을 작성하는 데 문제가 있습니다. 그 배열을 가져 와서 특정 방식으로 값을 랜덤 화하십시오. 라이더와 말을 적당한 위치에 배치하는 것은 수색 프로그램을위한 것입니다.규칙 집합으로 배열을 셔플하고 함수에서 값 반환
이 함수 (gen())에서 시도하려는 것은 [num2] 항목을 entry2 [num2]에 복사하는 것입니다. 여기서 num은 해당 항목의 양이고 num2는 임의로 생성 된 rand() 번호입니다. 나는 그 다음에 새로운 항목이 적어도 15 자리 이상 (이 경우에는 말의 라이더가 다음 이벤트 전에 휴식을 취할 수 있음)
정도로 추측 할 수 있도록 확인했습니다. 이 응용 프로그램은 작동하지 않습니다, 메신저 쉬운 방법이 있다고 생각하십니까? 변수를이 배열로 보내려면 어떻게해야합니까? 그리고이 함수가 배열을 내 메인으로 되돌릴 수있는 방법은 무엇입니까? 포인터를 통해 추측하고 있습니까?
아래에 전체 코드를 첨부했습니다. - 한, 그 사본을 랜덤 std::random_shuffle를 사용
