Solution

The output of the given program will be "yes".

Here's the step by step explanation:

  1. The #ifndef directive in C is a preprocessor directive that checks if the following macro is not defined. In this case, it checks if "san" is not defined.

  2. If "san" is not defined, the code between #ifndef and #endif will be included in the program. In this case, it would print "no". However, since "san" is not defined in the given code, this part will not be executed.

  3. After the #endif directive, the program continues with the rest of the code, which is printf("yes");. This will print "yes".

  4. Therefore, the output of the program is "yes".
