1. What is a data structure? Why is an array called a data structure? 2. What is a dynamic array? How is it created? Give a typical example of use of a dynamic array. 3. What happens when an array with a specified size is assigned (a) with values fewer than the specified size; and

(b) with values more than the specified size.

4. Discuss how initial values can be assigned to a multidimensional array. 1. Write a program for fitting a straight line through a set of points (xi, yi), i = 1,....,n.

The straight line equation is

y = mx + c

and the values of m and c are given y

All summations are from 1 to n.
