Run the following code and explain, using your own words, what is happening with each variable (w,x,y,z) and what is the difference between ++x and w++ (is there any influence on the result between prefix or postfix ++ operator?). Provide a snippet of the output. int main() int w = 20, x = 20; int y=5,z=5; y=y+(++x); z=2+ (w++); cout < < "x" < < x
