请高手帮忙用 c++ void Function 编写求学生平均分和Grade的程序

小弟初学者, 不知道自己写的错在哪里,请高手指点

#include<iostream>
#include<iomanip>
#include<string>

using namespace std;

void Greeting ();
void GetName (string &);
void ReadScores (double ,int&);
void ReportNoScores (string &);
double Calculation (double,double&);
char LetterGrade (double&);
void ReportData (string, double, double);
void Farewell();

int main()
{
string name;
char grade;
double total, average;
int count;

Greeting ();
GetName (name);
while (name != "")
{
ReadScores (total, count);
if (count ==0)
ReportNoScores (name);
else
{
average = Calculation (count, total);
grade = LetterGrade (average);
ReportData (name, average, grade);
}
GetName (name);
}
Farewell ();
return 0;
}

/*整个程序最大的两个问题一个是声明函数与实现函数时表有问题，多处严重不匹配，这个在编译时是检查不出来的，只能在链接时才会检查出来，然后就是字符串和字符的区别没弄清楚，当然还有一些小问题，比如不区分大小写之类的~~~修改后的程序如下*/
