My code i as follows: float radius; String msg="What is the radius of your circle? "; float area; String msg2="Your circle has an area of: "; float pi=3.14; void setup() { // put your setup code here, to run once: Serial.begin(9600); } void loop() { // put your main code here, to run repe…

Change the line ending setting on the serial monitor to "no line ending" or "none" or whatever gives no line-ending character like CR or LF, or both.. Please remember to use code tags when posting code

Coding tags? I am very new to this. Thank you so very much for your assistance.

Yes, that's right. The things that stop your posted code making no sense. (Hint: read it back and compare it to your actual code)

can you show me which line you are referring to? I will go back and look at the posting requirements for code. Thank you so very much. I started this just a few days ago and am now addicted.
