switch case

Question

why in this switch case the program executes the third case ??! cause we have 3 characters (h i -)??

switch (printf("hi-")) {
case 1: printf ("a"); break;
case 2: printf ("b"); break;
case 3: printf ("c"); break;
default: printf ("default"); }

//result hi-c

Yes, that seems to be true:

That might be because the printf is a function which actually writes text to a file, which will be used by command prompt to display data on the screen.

In Python you can write data to a file using write method and the written amount of characters will be returned as an integer.

Because printf also actually writes data to a file it could also return the amount of written characters.
