Question

Create a C++ project called lab3b and add the following source code init_struct.cpp to the project.

#include <iostream>

#include <string>

#include <iomanip>

using namespace std;

// This program demonstrates partially initialized structure variables

// PLACE YOUR NAME HERE

struct taxPayer

{

       string name;

       long socialSecNum;

       float taxRate; float income; float taxes;

};

int main()

{

       // Fill in code to initialize a structure variable named citizen1 so that

       // the first three members are initialized. Assume the name is Tim

       // McGuiness, the social security number is 255871234, and the tax rate is .35

       // Fill in code to initialize a structure variable named citizen2 so that

       // the first three members are initialized. Assume the name is John Kane,

       // the social security number is 278990582, and the tax rate is .29

       cout << fixed << showpoint << setprecision(2);

       // calculate taxes due for citizen1

       // Fill in code to prompt the user to enter this year's income for the citizen1

       // Fill in code to read in this income to the appropriate structure member

       // Fill in code to determine this year's taxes for citizen1

       cout << "Name: " << citizen1.name << endl;

       cout << "Social Security Number: " << citizen1.socialSecNum << endl;

       cout << "Taxes due for this year: $" << citizen1.taxes << endl << endl;

       // calculate taxes due for citizen2

       // Fill in code to prompt the user to enter this year's income for citizen2

       // Fill in code to read in this income to the appropriate structure member

       // Fill in code to determine this year's taxes for citizen2

       cout << "Name: " << citizen2.name << endl;

       cout << "Social Security Number: " << citizen2.socialSecNum << endl;

       cout << "Taxes due for this year: $" << citizen2.taxes << endl << endl;

       return 0;

}

Answer 1

Answer:

#include <iostream>

#include <string>

#include <iomanip>

using namespace std;

// This program demonstrates partially initialized structure variables

// PLACE YOUR NAME HERE

struct taxPayer

{

       string name;

       long socialSecNum;

       float taxRate; float income; float taxes;

};

int main()

{

       // Fill in code to initialize a structure variable named citizen1 so that

       // the first three members are initialized. Assume the name is Tim

       // McGuiness, the social security number is 255871234, and the tax rate is .35

       // Fill in code to initialize a structure variable named citizen2 so that

       // the first three members are initialized. Assume the name is John Kane,

       // the social security number is 278990582, and the tax rate is .29

       taxPayer citizen1,citizen2;

       citizen1.name="Tim McGuiness";
       citizen1.socialSecNum=255871234;
       citizen1.taxRate=0.35;

       citizen2.name="John Kane";
       citizen2.socialSecNum=278990582;
       citizen2.taxRate=0.29;

       cout << fixed << showpoint << setprecision(2);

       // calculate taxes due for citizen1

       // Fill in code to prompt the user to enter this year's income for the citizen1

      // Fill in code to read in this income to the appropriate structure member

       // Fill in code to determine this year's taxes for citizen1

       cout<<"Enter this year's income for citizen 1: ";
       cin>>citizen1.income;

       citizen1.taxes=citizen1.taxRate*citizen1.income;

       cout << "Name: " << citizen1.name << endl;

       cout << "Social Security Number: " << citizen1.socialSecNum << endl;

       cout << "Taxes due for this year: $" << citizen1.taxes << endl << endl;

       // calculate taxes due for citizen2

       // Fill in code to prompt the user to enter this year's income for citizen2

       // Fill in code to read in this income to the appropriate structure member

       // Fill in code to determine this year's taxes for citizen2

       cout<<"Enter this year's income for citizen 2: ";
       cin>>citizen2.income;

       citizen2.taxes=citizen2.taxRate*citizen2.income;

       cout << "Name: " << citizen2.name << endl;

       cout << "Social Security Number: " << citizen2.socialSecNum << endl;

       cout << "Taxes due for this year: $" << citizen2.taxes << endl << endl;

       return 0;

}

Output:
