I/O reading the next line in input file?

Hello, Im a newb so please go easy on me. Im trying to get my program to display a persons name (lastname, FirstName) whether they are high blood pressure or normal. Anyways I have all that figured out. What Im having problem with is the fact that I have no clue how to get it to read the next input line in my file.

My input file reads:
Smith Eleanore 110/73
Jones Tom 200/78

any help is appreciated.

Repeat the process (Line 27-31 provided from the posted source code).

The real problem is how are you going to store the next three data?

3 more variables? or array of 2?

    if( sys <= 119 && dia <= 79 )
        cout << ...

that helped it from repeating the same person but how to i get it to read the next person on the next line?

the output i got was
Smith, Eleanore has normal blood pressure at 110/73

i need it to output all the names and blood pressures in the file like that.

Thanks for that though I was not sure how to get the ignore into the while statement
