#include<conio.h>
int main()
{
	char fname[20];
   char lname[15];
	char grade;
   int age;
   cout<<"what is your first name?"<<endl;
   cin.get(fname,20);
   cout<<"what is your last name?"<<endl;
   cin.get(lname,15);
   cout<<"what letter grade do you deserve?"<<endl;
   cin>>grade;
   grade--;
   cout<<"what is your age?"<<endl;
   cin>>age;
   cout<<"name:"<<lname<<","<<fname<<endl;
   cout<<"grade:"<<grade<<endl;
   cout<<"age:"<<age<<endl;
   getch();
   return 0;
}

when the program runs it skips lname i don't know why

*** MOD EDIT: Added code tags. Please
