Basics of Switch in prograaming

Question

I am preparing for my school test. So for that I have visited lots of websites to clear my doubts about C, C++, Java programming languages. While I was reading those questions, I got one MCQ question which is below:

switch (printf("Do"))
{
    case 1:
        //code here
    case 2:
        //code here    
}

I execute this code and got execution of case 2 but I'm not getting why it is executed. Can any one help me to understand?

Because thats what `printf` returns. http://www.cplusplus.com/reference/cstdio/printf/ — tkausl, Jan 21 '19 at 05:24

printf returns the number of characters it has printed if successful. So in your case it returns 2 and therefore the code under case 2: is executed.
