   if (!strcmp(”cpp-programming.net”, “cpp-programming.net�”))
   printf(”hellon”);
   else
   printf(”hin”);

   ====> answer should print “hi” not “hello”

   int counter (int i)
   {
   static int count =0;
   count = count +i;
   return (count );
   }
   main()
   {
   int i , j;

   for (i=0; i <=5; i++)
   j = counter(i);
   }

   answer is 15, not 12.

   print()
   {
   int x = 3;
   switch(x)
   case 1:
   {
   printf("1");
   }
   break;
   case 2:
   {
   printf("2");
   case 3:
   printf("3");
   }
   break;
   default:
   printf("def");
   break;
   }

   answer is not 3 but compile error.

   Joe,

   regarding first one

   if (!strcmp(”cpp-programming.net”, “cpp-programming.net\0”))
     printf(”hello\n”);
   else
     printf(”hi\n”);
   

   ====> answer should print “hi” not “hello”

   Here, “cpp-programming.net”, “cpp-programming.net\0″ both strings are equal, strcmp returns zero if strings are equal, so here strcmp gets zero, and not zero is true, so “hello\n” printed, why do you think “Hi\n” should be printed??

   int counter (int i)
   {
     static int count =0;
     count = count +i;
     return (count );
   }
   main()
   {
     int i , j;
   
     for (i=0; i < =5; i++)
     j = counter(i);
   }
   

   >>answer is 15, not 12.
   Yes, this is correct. I'd corrected it.

   Regarding switch case program, I’d missed braces for switch, thanks for pointing out.
