배열 및 함수 호출로 카운트를 잃음

Question

현재 코드에서 프롬프트를 맨 위에 첨부했습니다. 나는 높은 값이나 낮은 값으로 힘든 시간을 보내고 있습니다. 나는 함수가 내 int main()보다는 오히려 호출되는 문제라고 믿지만 잘못 될 수있다. 가장 낮은 값은 기록되는 값이 아닙니다. 배열의 중간 또는 끝에 기본값이있는 것 같습니다 (6 월 또는 12 월은 내 Low로 출력되는 공통 월 임)

/* 
Write a program that lets the user enter the total 
rainfall for each of 12 months into an array of 
doubles. The program should calculate and display 
the total rainfall for the year, the average monthly 
rainfall, and the months wit hthe highest and lowest 
amounts. 

Input Validation: Do not accept negative numbers 
for monthly rainfall figures.

Answer 1

루프의 현재 최고점과 최저점을 업데이트하는 것을 잊었으므로 아래 두 가지 기능을 다시 작성하면 문제가 해결됩니다.

double RainLowpoint(double RainInput[], int size) 
{ 
    double LowPoint = RainInput[0]; 
    int LowCount = 0; 

    for (int count = 0; count < size; count++) //Find Lowest rainfall month through numerical comparison 
    { 
     if (RainInput[count] <= LowPoint) 
     { 
      LowCount = count; 
      LowPoint = RainInput[count]; // was missing 
     } 
    } 
    return LowCount; 
} 

double RainHighpoint(double RainInput[], int size) 
{ 
    double HighPoint = RainInput[0]; 
    int HighCount = 0; 

    for (int count = 0; count < size; count++) //Find Highest rainfall month through numerical comparison 
    { 
     if (RainInput[count] >= HighPoint) 
     { 
      HighCount = count; 
      HighPoint = RainInput[count]; // was missing 
     } 
    } 
    return HighCount; 
} 

당신은 또한 당신의 사용자 지정 코드를 삭제하고 표준 라이브러리 std::min_element 및 std::max_element에서 < 알고리즘 >를 사용할 수 있습니다.

Answer 2

당신의 LowPoint과 HighPoint 변수를 업데이트하십시오 :

if (RainInput[count] <= LowPoint) 
{ 
     LowCount = count; 
     LowPoint = RainInput[count]; 
} 

...에 StackOverflow에

if (RainInput[count] >= HighPoint) 
{ 
     HighCount = count; 
     HighPoint = RainInput[count]; 
}
