[C++] Anyone having issues with std::stod() here on SoloLearn?

Question

Alright, so std::stod() is a function that is part of the string header file / library. Its called via the std namespace though. Anyways, here's how it is used:

#include <iostream>
#include <string>

int main() {
double StringToDouble = std::stod("0.598372");
return 0;
}

This does NOT work here at SoloLearn in the code playground. You can test it out for yourself, although in every other compiler I can find it works perfectly fine. Anyone have a solution?

Answer 1

Here’s a simple solution:
std::string str = “0.827728262”;
double myDouble = atof(str.c_str());

Answer 2

Much thanks @Kurwius : )

Answer 3

I once tried and failed to use std::stoi which also supposedly return a number, though unlike std::stod it returns int rather than floating number, and I couldn't get it to work either. I ended having to write my own string to integer function.

Answer 4

@kurwius Thanks, that’s horrible though :(
