     2. In A,B,C are having some marbles with each of them. A has giben B and C the same number of marbles they
     already have to each of them. then, B gave C and A the same no. of marbles they have, then C gave A and B
     the same no. of marbles they have. At the end A,B,and C have equal no. of marbles.
            (i) If x,y,z are the marbles initially with A,B,C respectively. then the no of marbles B have at the

        }

3. What is an error in the following sequence of a program.
       
        int i;
        switch(i)
        {

                        break;
        }

4. what is an error in the following sequence of a program.
               
        int i;
        switch(i)
        {
                default: printf("This is default value");
                        break;

2.  Are the identifiers name and NAME are same?

3.  Is it right to type # of #define other than in first column?

4.  Does C require expressions to be enclosed in parenthesis for while loop?

5.  Will the preprocessor terminates with semicolon ?

6.  What is the return value of scanf statement?

7.  What will happen, if there are two statements (without grouping) in if
condition and an else is there for that if.

8.  What will be the output of this program.

        no_fish=1;
        if (no_fish==1)
                printf("The water was to warm\n");
        else ;
                printf("The wates were all fished out\n");

9.  Is parenthesis required for conditional expression in if condition?
