Tata Elxsi Technical C,C++ Paper

The test consisted of 2 sections one technical section 30 questions. to be answered in 30 minutes it included questions mostly on C and some 5-6 questions. on OS The C portion was difficult and the average score was around 15-20 The questions were totally different...not from Test your C skills... there were quite a few mistakes in printing so assume them accordingly some people told that quite a few questions. matched with a book C under DOS test so if can get that book it's well and good else be confident with what u know
