Single quote around the zero, or use 48.
str2.replace('"','0' );
str2.replace('"',48);

Try:
str2.replace("\"",0 );
I am trying to use the replace function on the variable str2 and store in str3 but encountering the above error. I don't understand the error. When I rem the replace line it works and the str2.substring works fine. How come substring works but replace wont????
thanks
String str2(sunset);
Serial.println(str2);
String str3 = str2.replace('"','0' );
Serial.println(str3);
Serial.println(str2.substring(9,23));
I don't understand the error.
You don't understand that the replace() method does not return a new String? Why not? The replace() method modifies the instance it is called for.
str2.replace('"','0' )
both the arguments to replace are single quoted ('...') denoting a single character.
Instead, use the double quotes ("...")
Thank you that worked
I wonder what worked?
