C++ read string with spaces

Solution 1
The format of your file seems to imply that the name of the city ends at the end of a line, not a space.
You can read that form using getline
char city[100];
int x , y;
f.open("map.txt");
while ( f ) {
f >> x >> y;
f.getline(city, 100);
}
f.close();
Solution 2
You can do something like this:
f.open("map.txt");
string city;
int x , y;
f >> x >> y;
getline(f,city);
while (!f.fail()) {
f >> x >> y;
getline(f,city);
}
f.close();
Solution 3
Use getline(f, city) for city. So, you have f >> x >> y; getline(f, city);
Solution 4
This code reads spaces and handles end of file correctly. None of the other answers do this I think
while ((f >> x >> y).getline(city, 100))
{
}
See this for more information on how to correctly test for end of file.
Of course you should be doing things the easy way using std::string
as others have said.

I have file like this:
59 137 New York 137 362 Syracuse 216 131 New Jersey ... .. .
and I would like to read it to a structure: X - Y - name of a city
char city[100]; int x , y; f.open("map.txt"); f >> x >> y >> city; while (!f.fail()) { f >> x >> y >> city; } f.close();
Problem is, that city reads only until next space, so from New York it reads only New. How should I read whole rest of a line, in some easy and smart way ?
