Error undeclared identifier in ideone

[mastersg7]

Hi all,

I am getting the following error when compiling. It does not recognize the declaration intNumberGuessed above i am guessing.

prog.cpp:29:20: error: use of undeclared identifier 'stod'
intNumberGuessed = stod(numberGuessed);
^
1 error generated.




#include <iostream>
#include <vector>
#include <string>
#include <fstream>

using namespace std;

int main(){



string numberGuessed;
int intNumberGuessed = 0;


do{

cout << "Guess a number between 1 and 10: ";

getline(cin, numberGuessed);


intNumberGuessed = stod(numberGuessed);

cout << intNumberGuessed << endl;


}while(intNumberGuessed != 4);


cout << "You win!" << endl;

return 0;
}
