Answer 1

Answer:

C error in the program..

Answer 2

There is error in the program.

Explanation:

Reason X has been declared outside the definition of add_list(). So any variable should be declared inside the function or procedure for  the function to have access on the variable. Otherwise, though it is visible to us, pro-grammatically it would not be visible to the procedure or function.

There are two ‘X’ used here, one in smaller case and another in capital. So each language consider variables in different way, some are not case-sensitive and some are case-insensitive.
