Regex would be good for this, here is an example :
I think you can change it to your specific case, e.g. reading your input line by line from a file.
#include <iostream>
#include <string>
#include <regex>
// helper function for showing the content of a vector.
// used to show you the content of each of the 5 vectors generated.
template<typename type_t>
void show(const std::vector<type_t>& values)
{
for (const auto& value : values)
{
std::cout << value << " ";
}
std::cout << std::endl;
}
int main()
{
// I didn't know what the firs 2 entries are so just called them v1, v2
// 5 vectors in total. (you could also opt for 1 vector of a struct holding the data)
std::vector<std::string> v1;
std::vector<std::string> v2;
std::vector<std::string> names;
std::vector<double> longitudes;
std::vector<double> lattitudes;
// This is a regex that will work on the input you gave
// also have a look at regex101.com you can
// test your own regexes there
// \\s+ matches one or more whitespaces
// group 1 : ([A-Z][0-9]{3}), matches one letter and exactly 3 numbers
// group 2 : ([A-Z]{3}), matches three letters
// group 3 : ([A-Z]+), matches one or more letters
// group 4 : ([0-9]+\\.[0-9]+), matches numbers with a . in it
// group 5 : ([0-9]+\\.[0-9]+), matches numbers with a . in it
std::regex rx{ "([A-Z][0-9]{3})\\s+([0-9]{3})\\s+([A-Z]+)\\s+([0-9]+\\.[0-9]+)\\s+([0-9]+\\.[0-9]+)" };
std::smatch match;
std::string input = { "A240 001 KERUL 41.857778 52.139167 A240 002 TABAB 40.903333 52.608333 A240 003 KRS 40.040278 53.012222 A240 004 KESEK 39.283333 55.566667 A240 005 INRAK 39.000000 56.300000 A242 001 HR 47.561667 6.732250" };
// in C++ you need to explicitly go over repeated occurences
auto begin = input.cbegin();
while (std::regex_search(begin, input.cend(), match, rx))
{
// groups end up in match array, group 1 at index 1, group 2 at index 2, etc..
// group[0] is the whole match, but we don't need it here.
v1.push_back(match[1]);
v2.push_back(match[2]);
names.push_back(match[3]);
// you can also convert the strings to doubles if needed.
longitudes.push_back(std::stod(match[4]));
lattitudes.push_back(std::stod(match[5]));
// skip forward to after match and look further
begin = match.suffix().first;
}
show(v1);
show(v2);
show(names);
show(longitudes);
show(lattitudes);
return 0;
}
