1. In the program given below, point out the error, if any, in the for loop.
   

   
   #include <studio.h>
   int main()
   {
          int i = 1;
         for (;;)
        {
             printf("%d\n", i++);
            if (i > 10)
           break;
        }
                return 0;
   }
                    

1. 1. There should be a condition in the for loop.

   
   
   

   2. The two semicolons should be dropped.

   
   
   

   3. The for loop should be replaced by a while loop.

   
   
   

   4. No error

3. Which of the following statement is correct about the program given below?
   

   
   
   #include <studio.h>
   int main ()
   {
   int i = 0;
   for(i = 0; i <= 127; printf ("%d", i++))
   ;
   printf ("\n");
   return 0;
   }
        

1. 1. The program would go in an infinite loop.

   
   
   

   2. The program would output 0 1 2 ..... 126 127.

   
   
   

   3. The program would not produce any output.

   
   
   

   4. The program would report an error: Cannot use printf() in for loop.

   {
   printf("%d",j );
   j = j + 1;
   }
   printf ( "\n");
