It is not a good idea to use the String (capital S) class on an Arduino as it can cause memory corruption in the small memory on an Arduino. Why is it an option then? It's in the Arduino language documentation, without any mention about possible corruption issues mentioned.C string prints the same as C++ String. C string array chars can be worked on directly in the array, it’s easier than with C++ String.

Add StringReserveCheck to other Strings as necessary.Mar 22, 2014 · You have to convert first your float to string, use dtostrf () or sprintf () then concat to your string. Also note that sprintf is very handy for compact creation of a (char) string: One point of caution though: sprintf () is a complex function, hence it is rather slow and uses quite some memory. As a real life Arduino example of the problems that arise from using c-string methods, see this Arduino Forum posting. The world will be a much better, safer place once people stop using c-strings all together. For text manipulation the Arduino Reference Language only lists String methods because they are easy and safe to use.I'm trying to concatenate a string and a floating point number to send to the serial monitor and the only way I can find to do it is using dtostrf(), but that seems a little clumsy. ... Great idea, except that sprintf() on the Arduino does not deal with floating point values. OP: Why do you feel it is necessary to concatenate the data before ...A C string is simply an array of characters, but it is an array of characters that must obey certain rules. ...

The strings are defined in the struct as char string[x], and given string values. To print out, I concatenate several strings into one longer string, and print it out via serial print command. So far, so good. Problem is that while it printed correctly in previous versions of my code, it does not print in a new version, with very little change from ... Add strings together in a variety of ways. because analogRead returns an integer. String concatenation can be very useful when you need to display a combination of values and the descriptions of those values into one String to display via serial communication, on an LCD display, over an Ethernet connection, or anywhere that Strings are useful.

Converts the contents of a String as a C-style, null-terminated string. Note that this gives direct access to the internal String buffer and should be used with care.
