Exl infotel placement questions:-

Hi, friends infotel visited my college. Aptitude exam was conducted in my college with technical 20 questions based on the “c” mainly they focused on the strings and pointers for CSE and IT students.Basically the aptitude exam is not online it is written test with multiple choice were given.I think to better to prepare aptitude questions from cool interview site.
Some of the questions are:-

1.)
const int perplexed = 2;
#define perplexed 3

main()

{

#ifdef perplexed
#undef perplexed
#define perplexed 4
#endif
printf(“%d”,perplexed);
}
