C++ and "Arduino" (to the extent that it can really be called a "language") don't do string interpolation. You basically have to cobble the string together yourself using snprintf or std::ostringstream (which you'd have on the ESP32). The Arduino String class also supports concatenation of non-string things onto the end of it..

Works the same as string.concat (). length is supposed be be the size of the buffer. The string knows how long it is. So, a better way to run this would be: char c [20]; s.toCharArray (c, sizeof (c)); Alternatively, you could initialize c with malloc, but then you'd have to free it later. Using the stack for things like this saves you time and keeps things simple.

This is called concatenation and it results in the original String being longer by the length of the String or character array with which you concatenate it. The + operator allows you to combine a String with another String, with a constant character array, an ASCII representation of a constant or variable number, or a constant character.Feb 23, 2020 · There are a few different methods of doing what you want. You do need to be careful when using c-strings (null-terminated char arrays) that you always allocate enough space for the terminating null character, which you are not doing with the data variables. strcpy() and strcat() require the terminating null, otherwise they will keep copying memory until they encounter a terminating null ...
