```//(Financial application: compute tax) Rewrite Listing 3.3, 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:
//i//nt brackets =
//{
// {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:
//tax = brackets * rates +
// (brackets – brackets) * rates +
//(brackets – brackets) * rates +
// (brackets – brackets) * rates +
// (brackets – brackets) * rates +
// (400000 – brackets) * rates
