Hey ankita, i wud suggest u start practising a bit of C++, although u can fairly manage with C, the efficiency of the program u use and the points u get for it, are goin to be decided on the fact that how small and yet effective is ur program. With C++, it is far more easier to write complex programs using easier and smaller codes, as it is an object-oriented lingo. So i wud say, side-by-side, prepare for C++.....and its not all that different....just a bit of object-oriented logic and some syntactical differences... there's nothin very different or difficult bout C++ as compared to C.....
