Interesting Problems of Switch statement in C/C++

1. Program 1 Output:

   Default: 

   Explanation: In switch, an expression "num+2" where num value is 2 and after addition the expression result is 4. Since there is no case defined with value 4 the default case got executed.
2. Program 2 Output:

   Bahubali

   Explanation: We can write case statement in any order including the default case. That default case may be first case, last case or in between the any case in the switch case statement. The value of expression "movie << (2 + movie)" is 8.
3. Program 3 Output:

   XYZ

   Explanation: In C, comma is also operator with least precedence. So if x = (a, b); Then x = b Note: Case expression can be macro constant.
4. Program 4

Output:

GEEKSFOR
