main.cpp： ：
#include #include <fstream> #include #include #include <vector> #include "student.h" using namespace std; int main() { vector stuList; double tuitionRate; ifstream infile; infile.open("GradeData.txt"); if(!infile) { cout<<"Input file does not exist."<<endl; return 1; } infile>>tuitionRate; string fName; int ID; //存储学生名和 ID int noOfCourses; char isPaid; //存储课程数存储 Y/N,用于表示是否交过学费 bool isTuitionPaid; string cName; //存储 true/false 和课程名 string cNo; int credits; //存储课程号和成绩 char grade; //存储学分 vector<course> courses; //存储课程信息的向量对象 course cTemp; student sTemp; infile>>fName; while(infile) { infile>>ID>>isPaid; if(isPaid == 'Y') isTuitionPaid = true; else isTuitionPaid = false; infile>>noOfCourses; courses.clear(); for(int i = 0; i < noOfCourses; i++) { infile>>cName>>cNo>>credits>>grade; cTemp.setCourse(cName, cNo, grade, credits); courses.push_back(cTemp); } sTemp.setInfo(fName, ID, isTuitionPaid, courses); stuList.push_back(sTemp); infile>>fName; } for(int count = 0; count < stuList.size(); count++) stuList[count].print(tuitionRate); infile.close(); return 0; }
student.cpp:
#include <vector> #include #include #include "student.h" #include "course.h" using namespace std; //设置学生信息 void student::setInfo(string fName, int ID, bool isTPaid, vector<course> courses) { stuname=fName; //设置姓名 sId = ID; //设置学生 ID isTuitionPaid = isTPaid; //设置是否交过学费 numberOfCourses = courses.size(); //设置课程数

course.cpp:
#include "course.h" void course::setCourse(string cName, string cNo, char grade, int credits) { courseName = cName; courseNo = cNo; courseGrade = grade; courseCredits = credits; } void course::print(bool isGrade) { cout<<left <<setw(8)<<courseNo<<" " <<setw(15)<<courseName; cout.unsetf(ios::left); cout<<setw(3)<<courseCredits<<" ";
以上为 main 函数
student.h:
#include <vector> #include #include #include "course.h" #ifndef student_h #define student_h using namespace std; class student:public course{ private: int sId; string stuname; int numberOfCourses; bool isTuitionPaid; vector<course> coursesEnrolled; public: void setInfo(string fName, int ID, bool isTPaid, vector<course> courses); student(); void print(double tuitionRate); int getHoursEnrolled(); double billingAmount(double tuitionRate); double getGpa(); }; #endif
