{
// Optional unionkeyword

today 6-12-2010 paper of cs201

paper was very easy with following discriptive questions.

1. difference between single dimentional array and multidimentional array
2. difference between a and a[10]
3. write a program to ask user for input and until the input is not equal to 'q' or 'Q' repeat asking for input.
4. which Functions used to read/write more than a single character or a single line while using Files?

5. What is difference B/W tellf() and tellp() difference in tellg() and tellp()








objective from past papers... subjective questions which i remem were like:

Q: multi dimensional array of 2 rows. assign first index of both rows '2'
Q: print the diagonal elements of a n-dimensional matrix
