Explanation / Answer
For question 4:
The code says if x=0, then return 2*x but else part is not there, so, in that case, the function will not be able to return any value in case x is not zero.
So, the function will not get complied and the function may not return any value.
For Question 5:
The argument is not a variable. It is an address of a variable.
For Question 6:
The function will not return any value.
