Please explain y+= ++x + "" + x;

Question

; lets take x= 6; y=0; n put your individual answer.

Answer 1

what i think is... y= 77. is this correct? yes, then explain please

Answer 2

Dear ,actually in the programming languages where this is must to declare the data type (in Java ,C,C++etc) before use ,then it will give an error. Other wise (in Java script) it will be typecasted in String , so in that case answer will be 077.

Answer 3

077 I would say, because you add an empty string, which change the type of your variable.

Answer 4

Hope I'm not answering bullshit but in my mind it should be:

y+ -> take actual value of y and add the following
++x -> it gets the actual value of x and increment it immediatly with 1
+ "" + -> add an empty string
+ x -> + x

Answer 5

Yes that's it, I just try.
