CodePudding user response:

E=D - Y the lack of a semicolon here, this is a mistake, the other you see again

CodePudding user response:

E=D - Y no error, is where I mark red error,

"W +" not w++

Nor W++ question,
My teacher give me something for a moment, after the file added a little Spaces,
Change after an error prompt has changed, but still error
