C++ Adresses line don't show up entirly when I try to read from file, Why?

I'm trying to read from one file which contains around 4000 fictional people. Looks like this in the reading file but with many more people following.

Justin Biber 
199403012345
London second street 12 33444, Miami

my task was to swap the names with the last name to look like this...

Lastname Firstname [M] //  Male  // Part one 
Bieber     Justin     // Part two 
London second street 12 33444, Miami  // part three

I have succeeded to solve part One and part Two but not part Three parts out of three. Some of the addresses from the reading file contain more lines and street names than I expected, I don't know how to handle it. For example, look at these two addresses examples...

Lastname Firstname [M] //  Male  // Part one 
Bieber     Justin     // Part two 
London second street 12 33444, Miami  // part three


Lastname Firstname [F] // female  // Part one
Roberts Julia  // Part Two
London second street 13 33676, lontime ev second  // Part Three 

As you can see the second address is longer. I guess my question is. How can I read the entire line no matter how long the addresses are?

This is my code...

Note: I have solved Part One and Two, However for the address part, I do not know how to get the whole line.
