Hello everyone
I want to convert some float values to string then concatenate both in order to add them to a link but it seems not to work . Below is my code, kindly have a look and tell me my mistake or error .
#include "mbed.h"
#include <iostream>
#include <string>
using std::string;
gpsCoordinates = gps.getGPS(&fix, &latitude, &longitude, &MSL_altitude, &speed_kph, &heading);
string str_lati(std::string(latitude));
string str_long(std::string(longitude));
string coord_string = str_lati + ' , ' + str_long ; // There is an error here
string c = "https://www.google.com/maps/place/@";
String map_link = c + coord_string ; // Here is the link to access the location on google map
// NB : the conversion to string has worked, but the concatenation thrown an error
Please note that , this is not the full code , I have just showed you the part for the issue, I will be grateful if you can help.
Thanks in advance .
