The below instruction stream illustrates a sequential computation that solves a linear problem. # do here all proper initializations. for (k = 0; k < n; k++) for (i = k+1; i < n; i++) { l = a[i][k] / a[k][k]; for (j = k+1; j < n; j++) a[i][j] = a[i][j] – l*a[k][j]; }

Assume the existence of a bankaccount class. define a derived class, savingsaccount that contains two instance variables: the first a double, named interestrate, and the second an integer named interesttype. the value of the interesttype variable can be 1 for simple interest and 2 for compound interest. there is also a constructor that accepts two parameters: a double that is used to initialize the interestrate variable, and a string that you may assume will contain either "simple", or "compound", and which should be used to initialize the interesttype variable appropriately. there should also be a pair of functions getinterestrate and getinteresttype that return the values of the corresponding data members (as double and int respectively).
