가능한 원인은 displayOutput()에 루프 조건이다.

for (int i = 0; rainArray[i] <= NUM_MONTHS; i++) 

그것은 아마도 rainArray의 모든 요소를 ​​통해 루프를 해야하는 : 여기에 라인입니다. 그러나 현재는 입력 데이터에 따라 임의의 횟수만큼 반복됩니다. 어레이의 끝을 지나가고 액세스하지 않아야하는 메모리에 액세스하려는 가능성이 완전히 있습니다.

오류 메시지가 표시 될 수 있습니다. 비록 당신이 테스트하고있는 입력 데이터가 무엇인지 알지 못한다면 확실하게 알기는 어렵습니다.

이에 루프를 변경해보십시오 :

for (int i = 0; i < NUM_MONTHS; i++)
