C++ defines a class and uses its member functions

Part Two of Learning C++

Create the GradeBook class

The running code is as follows:

#include <iostream>
#include <string>
using namespace std;

//定义一个类
class GradeBook
{
	public:
		void displayMassage( string courseName )
		{
			cout << "Welcome to the Grade Book for\n" << courseName << "!" << endl;
		}
		
};

int main()
{
	string nameOfCourse;
	GradeBook myGradeBook;//创建了一个名字叫myGradeBook的GradeBook的对象 
	cout << "Please enter the course name:" << endl;
	cin >> nameOfCourse;
	cout << endl;
	myGradeBook.displayMassage( nameOfCourse ) ;//使用对象的displayMassage（成员函数） 
	return 0;
}
