错误4错误LNK2019：函数___tmainCRTStartup芯片和莎莎类中引用了未解析的外部符号_main

代码如下; .h文件，然后.cpp;

#ifndef SALSA_H
#define SALSA_H

class Salsa
{
private:
    void getTotal();
    void getHigh();
    void getLow();
    int count;
    int total;
    int highest;
    int lowest;
    int flavor;
public:
    void getSold();
};
#endif

现在是.cpp;

#include "Salsa.h"
#include <iostream>
#include <string>
using namespace std;


void Salsa::getSold()
{
    for (count = 0; count < 5; count++)
    {
        cout << "Jar sold last month of ";
        cout << count + 1;
        cin >> flavor;

        while (flavor <= 0)
        {
            cout << "Jars sold must be greater than or equal to 0.";
            cout << "Re-enter jars sold for last month ";
            cin >> flavor;
            cout << endl;


        }
        Salsa::getTotal();
        Salsa::getHigh();
        Salsa::getLow();
    }

    Salsa::getTotal();

    total = 0;

    for (count = 0; count < 5; count++)
    {
        total += flavor;

        cout << "Total Sales: " << total << endl;
    }

    Salsa::getHigh();
    {
        highest = flavor;
        int index = 1;

        for (count = 0; count < 5; count++)
            if (flavor > highest)
            {
            highest = flavor;
            index = count + 1;
            }

        cout << "High Seller: " << flavor << endl;
    }

    Salsa::getLow();
    {
        lowest = flavor;
        int index = 1;

        for (count = 0; count < 5; count++)
        {
            if (flavor < lowest)
            {
                lowest = flavor;
                index = count + 1;
            }

            cout << "Low Seller: " << flavor << endl;
        }

        int main();
        {
            const int SALS_FLAV = 5;
            string flavor[SALS_FLAV] = { "mild", "medium", "sweet", "hot", "zesty" };

            Salsa sold;

            for (int index = 0; index < SALS_FLAV; index++)
            {
                sold.getSold();
            }
        }
    }
}

Answer 1

您的代码存在许多问题：

您没有声明函数的返回类型
您不应该使用;
您没有正确关闭功能，现在它们已成为嵌套功能

请研究您的代码与以下代码之间的差异：

#include "Salsa.h"
#include <iostream>
#include <string>
using namespace std;


void Salsa::getSold()
{
    for (count = 0; count < 5; count++)
    {
        cout << "Jar sold last month of ";
        cout << count + 1;
        cin >> flavor;

        while (flavor <= 0)
        {
            cout << "Jars sold must be greater than or equal to 0.";
            cout << "Re-enter jars sold for last month ";
            cin >> flavor;
            cout << endl;

        }
        getTotal();
        getHigh();
        getLow();
    }
}

void Salsa::getTotal()
{
    total = 0;

    for (count = 0; count < 5; count++)
    {
        total += flavor;

        cout << "Total Sales: " << total << endl;
    }
}

void Salsa::getHigh()
{
    highest = flavor;
    int index = 1;

    for (count = 0; count < 5; count++)
        if (flavor > highest)
        {
        highest = flavor;
        index = count + 1;
        }

    cout << "High Seller: " << flavor << endl;
}

void Salsa::getLow()
{
    lowest = flavor;
    int index = 1;

    for (count = 0; count < 5; count++)
    {
        if (flavor < lowest)
        {
            lowest = flavor;
            index = count + 1;
        }

        cout << "Low Seller: " << flavor << endl;
    }
}

int main()
{
    const int SALS_FLAV = 5;
    string flavor[SALS_FLAV] = { "mild", "medium", "sweet", "hot", "zesty" };

    Salsa sold;

    for (int index = 0; index < SALS_FLAV; index++)
    {
        sold.getSold();
    }
}
