Question

我正在为类编写代码，但是我不断收到-预期为'（'，用于函数式强制类型转换或类型构造-错误，提示说cout << void enterStolenMoonPies（int * array，int numDays）<

#include <iostream>
#include "Moonpie.h"
//#include "Functions.cpp"

using namespace std;

int* makeArray(int days);
void enterStolenMoonPies(int* array, int numDays);
int* totalMoonPies(int* array, int numDays);
float averageMoonPies(int numDays, int sum);
int* highestMoonPies(int* array, int numDays);
int* lowestMoonPies(int* array, int numDays);


int main()
{

    int days;

    cout <<"How many days did Jane steal moon pies?: ";
    cin >> days;

    cout << "Enter the number of moon pies stolen each day:";
    cout << void enterStolenMoonPies(int* array, int numDays) << endl;

    cout << "---------Results--------------"<< endl;

    cout << "Total number of Moon Pies stolen: ";
    int* totalMoonPies(int* array, int numDays);

    cout << "Average number of Moon Pies stolen per day: ";
    float averageMoonPies(int numDays, int sum);

    cout << "Highest amount of Moon Pies stolen in a day: ";
    int* highestMoonPies(int* array, int numDays);

    cout << "Lowest amount of Moon Pies stolen in a day: ";
    int* lowestMoonPies(int* array, int numDays);

}

这是标题：

#ifndef Moonpie_h
#define Moonpie_h

int* makeArray(int days);

void enterStolenMoonPies(int* array, int numDays);

int* totalMoonPies(int* array, int numDays);

float averageMoonPies(int numDays, int sum);

int* highestMoonPies(int* array, int numDays);

int* lowestMoonPies(int* array, int numDays);

#endif /* Moonpie_h */

这是函数文件：

#include <iostream>
//#include "Moonpie.cpp"



using namespace std;

int* makeArray(int days)
{
    int* numDays = new int[days];

    return numDays;
}



void enterStolenMoonPies(int* array, int numDays)
{
    int stolenMP = 0;

    for(int i =0; i<numDays; i++)
    {
        cout << "Enter the number of moon pies stolen each day:" << endl;
        cout << "Day " << i << ": ";
        cin >> stolenMP;
    }
}



int* totalMoonPies(int* array, int numDays)
{
    int* sum = 0;
    for(int i = 0; i < numDays; i++)
    {
        sum += array[i];
    }
    return sum;
}




float averageMoonPies(int numDays, int sum)
{
    float average;
    average = static_cast<float>(sum)/numDays;

    return average;
}




int* highestMoonPies(int* array, int numDays)
{
    int* highest;
    highest = &array[0];

    for(int i = 0; i <= numDays; i++)
        if (&array[i] > highest)
            highest = &array[i];

    return highest;
}



int* lowestMoonPies(int* array, int numDays)
{
    int* lowest;
    lowest = &array[0];

    for(int i = 0; i <= numDays; i++)
        if (&array[i] < lowest)
            lowest = &array[i];

    return lowest;
}

就像在注释中一样，您的代码在许多方面都不正确。您的函数不应被声明两次（标头中有一个，而源代码中有一个），但这只是众多问题中的一个。

cout << "Enter the number of moon pies stolen each day:";
cout << void enterStolenMoonPies(int* array, int numDays) << endl;

不起作用。至少应该是

cout << "Enter the number of moon pies stolen each day:";
cout << enterStolenMoonPies(array, numDays) << endl;

删除所有main函数声明，并包括相应的头文件。

您最好从一个简单的程序重新开始，并考虑将这些指针用于开始，因为它比较复杂。

如何为函数样式转换或类型构造修复此Expected'（'？
