infile wont read second time

[titanos]

Hi

I have this code

infile.getline(Firstname,size,'\n');
	infile>>Lastname;

        strcpy_s(CheckSentinal, Firstname); 
        strcat (CheckSentinal," ");	
        strcat ( CheckSentinal , Lastname );
	cout<< CheckSentinal<<endl;
	    
	

		for (int j=0;j<4;j++)
		{
			infile>>test_scores[b][j];
			cout<<test_scores[b][j]<<" ";
		}
		cout<<endl;
                infile.getline(Firstname,size);
		infile>>Lastname;
		cout<<Lastname<<endl;
		cout<<Firstname<<endl;
		strcpy_s(CheckSentinal,Firstname); 
        strcat (CheckSentinal," ");	
        strcat ( CheckSentinal,Lastname);
		cout<<CheckSentinal<<endl;

when im trying to read into Last name the second value it wont read it instead it read spaces

this is what it suppose to read from the file

George        
Washington    
96.8 99.9 97.7 95.6
John          
Adams        

and instead it prints

George        Washington
96.8 99.9 97.7 95.6
John          

what can I do to fix this please help me

Regards
Maor
