Because income is not <= 64000, we move to the else branch of the inner if statement (line 42).
if (income <= RATE1_MARRIED_LIMIT)
{
tax1 = RATE1 * income;
}
tax1 = RATE1 * income;
}
else
{
tax1 = RATE1 * RATE1_SINGLE_LIMIT;
tax2= RATE2* (income - RATE1_SINGLE_LIMIT);
}
else
{
}
The values of taxl and tax2 are updated.
{
tax1 = RATE1 * RATE1_MARRIED_LIMIT;
tax2 = RATE2 * (income - RATE1 MARRIED_LIMIT);
}
tax1 = RATE1* RATE1_MARRIED_LIMIT;
tax2 = RATE2* (income - RATE1 MARRIED_LIMIT);

Their sum total_tax is computed and printed. Then the program ends.

Because the program trace shows the expected output ($10,400), it successfully demon-
double total_tax = tax1 + tax2;

return 0;

For example, let's trace the tax program with the data from the program run in Section 3.4. In
lines 13 and 14, taxl and tax2 are initialized to 0.

double tax1 = 0;
double tax2 = 0;
In lines 18 and 22, income and marital status are initialized by input statements.
double income;

cin >> income;
marital
tax tax2 income, status
