Question

C++ Programming

In this project, we will be reading in data, performing some calculations and doing formatted output.

Our program will be calculating very simple "taxes" for a user. Start by prompting for the users full name. Then ask them for their gross income. Then prompt them for their deductions. After this, prompt them for the tax rate on their income after deductions. Finally, display how much they owe in taxes in a nicely formatted output. In this output, ensure that the calculations are shown to 2 digits of precision after the decimal point and that the tax rate is displayed to 3 digits of precision after the decimal point.

Answer 1

#include<iostream>

#include<iomanip>

using namespace std;

int main()

{

    string name;

   

    cout<<"Enter your name : ";

    getline(cin, name);

   

    double gross, deductions, tax_rate;

   

    cout<<"\nEnter the gross income : ";

    cin>>gross;

   

    cout<<"\nEnter the deductions : ";

    cin>>deductions;

   

    cout<<"\nEnter the tax rate : ";

    cin>>tax_rate;

   

    // convert tax percentage into fraction

    tax_rate = tax_rate / 100.0;

   

    // calculate total tax

    double tax = (gross - deductions) * tax_rate;

   

    cout<<"name               : "<<name<<endl;

    cout<<"Gross Income       : $";

    cout<<setprecision(2)<<gross<<endl;

    cout<<"Deductions         : $";

    cout<<setprecision(2)<<deductions<<endl;

    cout<<"Total Tax Payable : $";

    cout<<setprecision(3)<<tax<<endl;

   

    return 0;

}

Sample Output
