#includeint main()
{using namespace std;
	char firname[15], lastname[10], lettergrade, outgrade;
	unsigned int age;
	cout<< "What is your first name? ";
	cin >>firname;
	cout<< "What is your lastname? ";
	cin >>lastname;
	cout<< "What letter grade do you deserve? ";
	cin >>lettergrade;
	switch (lettergrade) {case 'A':
			outgrade = 'B';
		case'B':
			outgrade = 'C';
		case'C':
			outgrade = 'D';
		case'D':
			outgrade = 'A';
	}
	cout<< "What is your age? ";
	cin >>age;
	cout<< "Name: "<< lastname<< ", "<< firname<< endl
		<< "Grade: "<< outgrade<< endl
		<< "Age: "<< age<< endl;
	return 0;
}

2023/1/16更新如下:

#include#includeint main()
{using namespace std;
	string firname, lastname;
	char lettergrade;
	unsigned int age;
	cout<< "What is your first name? ";
	cin >>firname;
	cout<< "What is your lastname? ";
	cin >>lastname;
	cout<< "What letter grade do you deserve? ";
	cin >>lettergrade;
	cout<< "What is your age? ";
	cin >>age;
	cout<< "Name: "<< lastname<< ", "<< firname<< endl
		<< "Grade: "<< ++lettergrade<< endl
		<< "Age: "<< age<< endl;
	return 0;
}
二 cin.getline(name,ArSize);报错(待解)

在这里插入图片描述

//instr2.cpp -- reading more than one word with getline
#include#includeint main()
{using namespace std;
	const int ArSize = 20;
	string name, dessert;
	cout<< "Enter your name:\n";
	getline(cin,name);
	cout<< "Enter your favorite dessert:\n";
	getline(cin,dessert);
	cout<< "I hace some delious "<< dessert
		<< " for you, "<< name<< ".\n";
	return 0;
}

使用cin.getline(name,ArSize);会报错,待解;截图如下
