Thanks for the pointers Dietmar.
My code works perfectly fine, thanks to your hack. Here is how it looks
like.
#include <iostream>
#include <locale>
#include <algorithm>
#include <sstream>
#include <string>
#include <ios>
using std::ios;
using std::string;
using std::istringstream;
using std::cout;
using std::endl;
struct commactype: std::ctype<char> {
commactype(): std::ctype<char>(get_table()) {}
static std::ctype_base::mask const* get_table() {
static std::ctype_base::mask* rc = 0;
if (rc == 0) {
rc = new
std::ctype_base::mask[std::ctype<char>::table_size];
std::fill_n(rc, std::ctype<char>::table_size,
std::ctype_base::mask());
rc[','] = std::ctype_base::space;
}
return rc;
}
};
void ProcessLine(const std::string & line) ;
int main() {
string line1 = "1,429946.2844";
string line2 = "1 429946.2844";
ProcessLine(line1);
ProcessLine(line2);
}
void ProcessLine(const std::string & line) {
istringstream iss(line);
iss.imbue(std::locale(std::locale(), new commactype));
int a;
long double b;
iss >> a >> b;
std::cout.setf(ios::fixed);
cout << line << " <-- parsed to --> " << a << " : " << b << endl;
}
I have a question though. Once we change the locale using 'imbue' ,
would it be still valid / possible to return to the default locale ?
Thanks for your help.
