c++ - Read a line from the console -

i reading several string such name , surname , student number , grades, first 3 have done follows:

 cout<<"enter student's first name: "<<endl;             string name;             cin>>name;             cout<<"enter student's last name: "<<endl;             string surname;             cin>>surname;             cout<<"enter student's unique student number: "<<endl;             string studentno;             cin>>studentno; 

how grades enter in following manner : " 90 78 65 33 22" , want read entire line of grade string variable. these string used construct student object.

how achieve this, tried using getline() not work.

my attempt:

 int main(){  cout<<"enter student's first name: "<<endl;                 string name;                 cin>>name;                 cout<<"enter student's last name: "<<endl;                 string surname;                 cin>>surname;                 cout<<"enter student's unique student number: "<<endl;                 string studentno;                 cin>>studentno;                 string classrcd;                std::getline(cin , classrcd);                db.add_student( name , surname , studentno , classrcd);      /*creates student object , add list in db of type database*/                clear();  //clears screen in while loop   return 0; } 

you still have new line in stream after cin>>studentno, giving empty string classrcd.

you solve adding getline() call after cin>>studentno , leaving alone result, or ignore new line std::cin.ignore(std::numeric_limits<std::streamsize>::max(), '\n');
