[C++] getting multiple arguments

[yun4]

Hi, i'm creating a c++ program that needs to take in multiple arguments. the arguments are 2 doubles and a string (double double string) but it gets worst, i need to save those arguments for later manipulation but the program needs to take multiple lines of arguments until indicated by an empty line(meaning the end of input).

double double string
double double string
...

i'm preparing to save the arguments in lists

List<double> x, y;
List<String> name;

but i don't know how to extract the arguments. i've look at get() and getline() but not sure how to implement it. Thanks in advance.
