(Financial application: compute tax) Rewrite Listing, ComputeTax.cpp, using arrays. For each filing status, there are six tax rates. Each rate is applied to a certain amount of taxable income. For example, from the taxable income of $400,000 for a single filer, $8,350 is taxed at 10%, (33,950-8,350) at 15%, (82,250-33,950) at 25%, (171,550-82,550) at 28%, (372,550-82,250) at 33%, and (400,000-372,950) at 36%. The six rates are the same for all filing statuses, which can be represented in the following array:

double rates[] = {0.10, 0.15, 0.25, 0.28, 0.33, 0.36};

The brackets for each rate for all the filing statuses can be represented in a two­dimensional array as follows:

int brackets[4][5] ={{8350, 33950, 82250, 171550, 372950}, // Single filer{16700, 67900, 137050, 20885, 372950}, // Married jointly// or qualifying // widow(er){8350, 33950, 68525, 104425, 186475}, // Married separately{11950, 45500, 117450, 190200, 372950} // Head of household};

Suppose the taxable income is $400,000 for single filers. The tax can be computed as follows:

t

ax = brackets[0][0] * rates[0] +(brackets[0][1] - brackets[0][0]) * rates[1] +(brackets[0][2] - brackets[0][1]) * rates[2] +(brackets[0][3] - brackets[0][2]) * rates[3] +(brackets[0][4] - brackets[0][3]) * rates[4] +(400000 - brackets[0][4]) * rates[5]
