Can you please provide the full error message; there should be a button "Copy error messages" in the orange bar when compilation fails. Click it and next paste here in a reply.
i cant change location
What does that mean? If you want to move the topic, that's already done. If something else, please elaborate.
This Is The Error
C:\Users\Admin\Downloads\led\led.ino: In function 'void setup()':

i changed the topic
Lose the "const char"
It's still / again in the wrong section Installation and Troubleshooting is not for problems with your project See About the Installation & Troubleshooting category.
done
It's again in the wrong category. I will move it, please leave it where I put it.
