C++编译器无法识别头文件

我是C++新手。我正在尝试练习在Visual Studio上编译程序，但是在破译编译器错误时遇到了一些麻烦。我真的可以使用一些帮助来弄清楚如何正确调试和编译程序，这样我将来编译代码就不会有太多麻烦。

我有三个文件：Gradebook.h，Gradebook.cpp和Source1.cpp。Gradebook.h 位于头文件中，另外两个位于解决方案资源管理器的源文件中。

编辑：我有一堆语法错误和其他不必要的注释，这使我难以阅读自己的代码。(感谢雷和其他所有人(。以下是我修改后的代码。我还发现了如何正确使用代码示例工具，所以现在一切都应该正确缩进。

    #include <string>
    using namespace std;
    class GradeBook
    {
    public:
        //constants
        static const int students = 10; //number of tests
        static const int tests = 3;  //number of tests
        //constructor initializes course name and array of grades
        string Gradebook(string, const int[][tests]);
        void setCourseName(string); //function to set course name
        string getCourseName(); //function to retrieve the course name
        void displayMessage(); //display a welcome message
        void processGrades(); //perform various operations on the grade data
        int getMinimum(); //find the minimum grade in the grade book
        int getMaximum(); //find the maximum grade in the grade book
        double getAverage(const int[], const int); // get student's average
        void outputBarChart(); //output bar chart of grade dist
        void outputGrades(); //output the contents of the grades array
    private:
        string courseName; //course name for this gradebook
        int grades[students][tests]; //two-dimensional array of grades
    }; //end class GradeBook
I don't get any errors in Gradebook.h, but the main problem lies in my other source files:
#include <iostream>
#include <iomanip>
using namespace std;
//include definition of class GradeBook from GradeBook.h
#include "GradeBook.h"
// two-argument constructor initializes courseName and grades array
GradeBook:: GradeBook(string name, const int gradesArray[][GradeBook::tests])

    setCourseName(name); //initialize coursename
    //copy grades from gradeArray to grades
    for (int student = 0; student < students; ++student)
        for (int tests = 0; tests < tests; ++tests)
            grades[student][tests] = gradesArray[student][tests];

    return courseName;
} 
//display a welcome message to GradeBook user
void GradeBook::displayMessage()
{
    //statements calls getCourseName to get the name of the course the gradebook represents
    cout << "Welcome to the grade book for n" << getCourseName() << "!"
        << endl;
}

void GradeBook::processGrades()

    outputGrades(); //output grades array
    // call functions getMinimum and getMaximum
    cout << "nLowest grade in the grade book is " << getMinimum()

    outputBarChart(); //display distribution chart of grades on all tests
} 
//find minimum grade in the entire Gradebook
int GradeBook::getMinimum()
{
    int lowGrade = 100; //assume lowest grade is 100;
    //loop through rows of grades array
    for (int student = 0; student < students; ++student)
    {
        //loop to columns of current row
        for (int tests = 0; tests < tests; ++tests)
        {
            //if current grade less than lowGrade, assign it to lowGrade
            if (grades[student][tests] < lowGrade)
                lowGrade = grades[student][tests]; //new lowest grade
        }
    } 
    return lowGrade; 
}

int GradeBook::getMaximum()
{
    int highGrade = 0; //assume highest grade is 0
    for (int student = 0; student < students; ++student)
    {
        //loop to columns of current row
        for (int tests = 0; tests < tests; ++tests)
        {
            //if current grade less than highGrade, assign it to highGrade
            if (grades[student][tests] > highGrade)
                highGrade = grades[student][tests]; //new highest grade
        }
    }  
    return highGrade; 
} 
//determine average grade for particular set of grades
double GradeBook::getAverage(const int setOfGrades[], const int grades)
{
    int total = 0; //initialize total
    //sum grades in array
    for (int grade = 0; grade < grades; ++grade)
        total += setOfGrades[grade];
    //return average of grades
    return static_cast <double>(total) / grades;
} 
//output bar chart displaying grade distribution
void GradeBook::outputBarChart()
{
    cout << "nOverall grade distribution: " << endl;
    //stores frequency of grades in each range of 10 grades

    int frequency[frequencySize] = {}; //initalize elements to 0;
    //for each grade, increment the appropriate frequency
    for (int student = 0; student < students; ++student)
        for (int tests = 0; tests < tests; ++tests)
            ++frequency[grades[student][tests] / 10];
    //for each grade frequency, print bar in chart
    for (int count = 0; count < frequencySize; ++count)

        if (count == 0)
            cout << "0-9: ";
        else if (count == 10)
            cout << "100: ";
        else
            cout << count * 10 << "-" << (count * 10) + 9 << ": ";
        //print bar of asterisks
        for (int stars = 0; stars < frequency[count]; stars)
            cout << '*';
        cout << endl;
    }
}
//output the contents of the grades array
void GradeBook::outputGrades()
{
    cout << "nThe grades are: nn";
    cout << "             "; //align column heads
    //create a column heading for each of the tests
    for (int tests = 0; tests < tests; ++tests)
        cout << "Test" << tests + 1 << " ";
    cout << "Average" << endl; //student average column heading

            cout << setw(8) << grades[student][tests];
        //call member function getAverage to calculate student's average
        //pass row of grades and the value of tests as the arguments
        double average = getAverage(grades[student], tests);
        cout << setw(9) << setprecision(2) << fixed << average << endl;
    }
}

我在这里收到的主要错误如下：

GradeBook:: GradeBook(string name, const int gradesArray[][GradeBook::tests])

错误：没有重载函数"成绩簿：：成绩簿"的实例与指定的类型匹配。

GradeBook::Gradebook(string, const int[][tests])
{
}

显式类型缺失(假定为"int"(和错误：声明与"std：：string Gradebook(在第 12 行声明("不兼容。

我真的很困惑和沮丧。您可以提供的任何见解都将非常有帮助。这是我教科书中的一个例子，几乎是逐字逐句的，在过去的两个小时里，我一直在试图找出缺少什么。

我拥有的最后一个源文件如下：

#include "Gradebook.h"
#include "Source1.h"
//function main begins program execution
int main()
{
    //two-dimensional array of student grades
    int gradesArray[ GradeBook::students][GradeBook::tests] =
    {
        {87, 96, 70},
        {68, 87, 90},
        {94, 100, 90},
        {100, 81, 82},
        {83, 65, 85},
        {78, 87, 65},
        {85, 75, 83},
        {91, 94, 100},
        {76, 72, 84},
        {87, 93, 73}
    }
GradeBook myGradebook("CS101 Introduction to C++ Programming", gradesArray);
myGradeBook.displayMessage();
myGradeBook.processGrades();
} //end main

我在最后几行收到错误：成绩簿 myGradebook("xxxx"( 收到错误：预期为";" ..但是我不是已经有一个了吗？

和 myGradebook.displayMessage((;错误：标识符"我的成绩簿"未定义。

请指教并指出我正确的方向。我迫切需要帮助。
