Answer:

One shall practice these interview questions to improve their C programming skills ... #include <stdio.h >; int main(); {; int x = 1;; short int i = 2;; float f = 3;; if ( sizeof((x == 2) ... else if (sizeof((x == 2) ? f : i) == sizeof( short int))

Answer 2

Compilation error (Option D).

A compilation error will arise due to the "if" statement. Here in the if statement instead of giving a condition an undefined constant 'x' is written and due to this a compilation error will rise the program will stop.

To remove the error just give a condition in the if statement and give a value to the constant.
