How to set the enviorment variable?

I’m a beginner for studying cuda, but I don’t know how to set the enviorment variable. Because I have read some article that you must set some enviorment variables first when you build cuda code.
Thanks

if you have installed CUDA SDK and toolkit you should already have the environment variables.

press window + pause in your keyboard to open system properties window. go to advanced -> environment variables
check if you have CUDA’s, if you don’t just create them :)

Thanks for your reply. :)

I see.
