Use you project 1 (or similar one that you wrote) with header and cpp in same fi

Question

Use you project 1 (or similar one that you wrote) with header and cpp in same file to write data to a random access (binary) file. Also include a program that reads the file. Please note that instead of string you need to use array of characters. See "writing to binary" and "reading from binary" examples.

My code:

headfile

#include <iostream>

#include <string.h>

using namespace std;

class data {

char name1[20], name2[20], name3[20], name4[20], name5[20];

float sal1, sal2, sal3, sal4, sal5;

int h_year1, h_year2, h_year3, h_year4, h_year5;

int year, years[5], i;

public:

void setNames(char na1[], char na2[], char na3[], char na4[], char na5[]) {

strcpy_s(name1, na1);

strcpy_s(name2, na2);

strcpy_s(name3, na3);

strcpy_s(name4, na4);

strcpy_s(name5, na5);

}

void setSalaries(float sa1, float sa2, float sa3, float sa4, float sa5) {

sal1 = sa1;

sal2 = sa2;

sal3 = sa3;

sal4 = sa4;

sal5 = sa5;

}

void setHire_years(int y1, int y2, int y3, int y4, int y5) {

h_year1 = y1;

h_year2 = y2;

h_year3 = y3;

h_year4 = y4;

h_year5 = y5;

}

void year_person_hired() {

year = 2017;

i = 0;

years[i++] = year - h_year1;

years[i++] = year - h_year2;

years[i++] = year - h_year3;

years[i++] = year - h_year4;

years[i++] = year - h_year5;

}

void print_data() {

cout << "Person Name Salary Hire_date Years since person hired" << endl;

cout << name1 << " " << sal1 << " " << h_year1 << " " << years[0] << endl;

cout << name2 << " " << sal2 << " " << h_year2 << " " << years[1] << endl;

cout << name3 << " " << sal3 << " " << h_year3 << " " << years[2] << endl;

cout << name4 << " " << sal4 << " " << h_year4 << " " << years[3] << endl;

cout << name5 << " " << sal5 << " " << h_year5 << " " << years[4] << endl;

}

};

CPP:

#include <iostream>

#include <string.h>

#include "data.h"

using namespace std;

int main()

{

int setNames;

int setSalaries;

int setHire_years;

int DTSETNAMES;

int DTSETSALARIES;

data dt;

char names[5][10];

float sal[5];

int y[5], i;

cout << "Enter Names of 5 Persons" << endl;

for (i = 0; i < 5; i++)

cin >> names[i];

dt.setNames(names[0], names[1], names[2], names[3], names[4]);

cout << "Enter Salaries of 5 Persons" << endl;

for (i = 0; i < 5; i++)

cin >> sal[i];

dt.setSalaries(sal[0], sal[1], sal[2], sal[3], sal[4]);

cout << "Enter Hire_dates of 5 Persons" << endl;

for (i = 0; i < 5; i++)

cin >> y[i];

return 0;

};
