1. n’ numbers.

PART B — (5 ´ 16 = 80 marks)

11.Write a modular program in C to perform addition, subtraction and multiplication of two matrices of order ‘n ´ n’ and find  where

1. A, B, C and D are ‘n ´ n’ matrices.
2. 12.(a)Differentiate ‘‘while’’ statement and ‘‘do–while’’ statement with an example program.

Or
