带传递参数的问题

Question

此代码使用Typedef数组返回表单函数的值。

// This program will read in a group of test scores (positive integers from 1 to 100)
// from the keyboard and then calculate and output the average score
// as well as the highest and lowest score. There will be a maximum of 100 scores.

// Najah Johnson

#include <iostream>
using namespace std;

typedef int GradeType[100];             // declares a new data type:
                                                            // an integer array of 100 elements

float findAverage(const GradeType, int);        // finds average of all grades
int  findHighest(const GradeType, int);         // finds highest of all grades
int  findLowest(const GradeType, int);          // finds lowest of all grades

int main()
{
    GradeType grades;       // the array holding the grades.
    int numberOfGrades;     // the number of grades read.
    int pos;                        // index to the array.
    float avgOfGrades;      // contains the average of the grades.
    int highestGrade;       // contains the highest grade.
    int lowestGrade;        // contains the lowest grade.


    // Read in the values into the array

    pos = 0;
    cout << "Please input a grade from 1 to 100, (or -99 to stop)" << endl;
    cin >>  grades[pos];

    while (grades[pos] != -99)

            grades[pos] = 
            pos ++;

            cout << "The total number of grades entered is: " << grades[pos] << endl;


            // Fill in the code to read the grades
    }




    numberOfGrades = pos;   // Fill blank with appropriate identifier

    // call to the function to find average
    avgOfGrades = findAverage(grades, numberOfGrades);

    cout << endl << "The average of all the grades is " << avgOfGrades << endl;


   highestGrade = findHighest(GradeType, size);
    // Fill in the call to the function that calculates highest grade

这是我删除的问题的代码的更新版本，以便每个人都可以获取全部要点。这是我的代码遇到的三个问题：

#main.cpp: In function ‘int main()’:
#main.cpp:55:44: error: expected primary-expression before ‘,’ token
    highestGrade = findHighest(GradeType, size);
                                        ^
#main.cpp:55:46: error: ‘size’ was not declared in this scope
    highestGrade = findHighest(GradeType, size);
                                          ^~~~
#main.cpp:61:41: error: expected primary-expression before ‘,’ token
   lowestGrade = findLowest(GradeType, size);
                                     ^

如您所见，它们都与我的函数调用的参数有关。如果有人想知道的话，该程序是C ++。
