    s.setkv(i,y);
	cout<<"\n\n\tThe typed information are : ";
    p.printinfo();
    s.printkv();
cin.get();cin.get();
return 0;

}

推荐答案

cout<<"\n\nName of student: ";
	cin>>name;

如果您仅在此处按Enter，会发生什么?变量name将不包含任何内容.您应该检查这种情况并采取一些措施.想想如果您是计算机会做什么.

What happens if you just push enter here? The variable name will not contain anything; matbe you should check for that situation and take some action. Think what you would do if you were the computer.
