Revisions to How to retrieve the data type of a variable?

The correct name for the concept is, I believe, function overloading and not polymorphism

I use a simple stupid approach...

// serial print variable type
void types(String a) { Serial.println("it's a String"); }
void types(int a) { Serial.println("it's an int"); }
void types(char *a) { Serial.println("it's a char*"); }
void types(float a) { Serial.println("it's a float"); }
void types(bool a) { Serial.println("it's a bool"); }

This is the concept of polymorphismfunction overloading where multiple functions with different parameter types are created but with the same function name. During run time, the function matching the right number of arguments and argument type(s) will get called. Hope this explanation helps.

Added language tag of C, ran auto-formatter, added bool type

In the Arduino IDE, you are unable to use typeof as it results in errors. Rather, you can use an alternative variable name, for example "types".
