Identify syntax error

Question

Find the $C$ statement which has a syntax error.

1. If (z)
2. For (a, b, c)
3. While (a, b)
4. None of these.

Answer 1

D) None Of these .

As C language is case sensitive, it treats them as function declaration or function calling [depending where those used].

Answer 2

Actually c language is case sensitive so answer is option (d)

But this question has a typo with first letter as capital in each options then option is (b) because both option a and c has no syntax error.

a)  if(z)  ' if ' can accepts integer identifier as well in place of logical expression.

c) comma is operator so it can result into either a or b depending on their values.

See these references : http://www.geeksforgeeks.org/a-comma-operator-question/ and http://ideone.com/KB8Beo

b) This option is wrong because for(a,b,c) is not a correct syntax because for accepts semicolon ' ; ' not comma ' , '.
