Grabbing the numbers from a string and storing them
How would I go about grabbing numbers in a string and storing them into a variable?
Example: A user inputs longitude and latitude along with the locations name
20.8987/N 156.4305/W Kahului Airport
47.4647/N 8.5492/E Zurich Airport
How do I read each line, get the numbers(doubles) that I want, as well as the location name? And store each in their appropriate variable

How do I read each line:
user input: http://www.cplusplus.com/reference/istream/istream/getline/
input file: http://www.cplusplus.com/doc/tutorial/files/
get the numbers(doubles) that I want:
http://www.cplusplus.com/reference/cstring/strtok/
http://www.cplusplus.com/reference/string/string/substr/
http://www.cplusplus.com/reference/string/stof/
as well as the location name:
Should be trivial now.
