I wrote this code, why is wrong?

Look at the beginning of node_m and have_touch definition

CodePudding user response:

Error means you have no initialization,

CodePudding user response:

I can emersion the question, in adding the right header file and the using instructions, and a correct node won't appear above problems after class,

CodePudding user response:

reference 1st floor zjq9931 response:

error means you have no initialization,

I'm not have been initialized

CodePudding user response:

refer to the second floor Constructor_ response:

I can emersion the question, in adding the right header file and the using instructions, and a correct node won't appear above problems after class,

Never used, may be in the class header file initialization is in it? Not sure, don't know, sorry.
