Q:

#define clrscr() 100

main()

{

clrscr();

printf( "%dn", clrscr() );

}

A) 100 B) 0
C) Compilation error D) Exception occurs
 
Answer & Explanation Answer: A) 100

Explanation:

Preprocessor executes as a seperate pass before the execution of the compiler. So textual replacement of clrscr() to 100 occurs.The input program to compiler looks like this :

main ()

{

100;

printf("%d\n",100);

}

Note: 100; is an executable statement but with no action. So it doesn't give any problem.

Q:

If  1 1 1 1 = R
    2 2 2 2 = T
    3 3 3 3 = E
    4 4 4 4 = N

 

Then  5 5 5 5 = ?

A) Y B) Z
C) T D) X
 
Answer & Explanation Answer: A) Y

Explanation:

If you add all the terms of the LHS of equality, then the last letter of the sum written in words would give you the RHS.

1 + 1 + 1 + 1 = 4 = FOUR

2 + 2 + 2 + 2 = 8 = EIGHT

3 + 3 + 3 + 3 = 12 = TWELVE

4 + 4 + 4 + 4 = 16 = SIXTEEN

 

So, following the same pattern.

5 + 5 + 5 + 5 = 20 = TWENTY

 

That gives us our answer to 5 5 5 5 =  "Y".
