Question

This is C++. The task is to convert the program to make use of fucntions, but I am am struggling to figure out how to do so.

#include <iostream>
#include <iomanip>
using namespace std;
main(){
char empid[ 100 ][ 12 ];   
char fname[ 100 ][ 14 ], lastname[ 100 ][ 15 ];
int hw[ 100 ];
double gp[ 100 ], np[ 100 ], hr[ 100 ], taxrate[100], taxamt[ 100 ];
int counter = 0;
int i;
cout<<"ENTER EMP ID, FNAME, LNAME, HRS WORKED, HRLY RATE ctrl z to end"<<endl;
while( cin>>empid[counter]>>fname[counter]>>lastname[counter]>>hw[counter]>> hr[counter])
counter=counter+1;
for ( i=0; i<counter; i++){
gp[i] = hw[i] * hr[i];}//end grosspay for loop
for (i=0; i<counter; i++){
if (gp[i]>500) taxrate[i] = .30;
               else if (gp[i]>200) taxrate[i]=.20;
else taxrate[i] = .10;
}// FOR
for ( i=0; i<counter; i++){
taxamt[i] = gp[i] * taxrate[i];}//end taxamount for loop
for ( i=0; i<counter; i++){
np[i] = gp[i] - taxamt[i];}//end netpay for loop
cout<<endl;
cout<<setw(14)<<"EMPLOYEE ID"<<setw(16)<<"FIRST NAME"<<setw(17)
<<"LAST NAME" <<setw(4)<<"HW"<<setw(5)<<"HR"<<setw(6)
<<"GROSS"<<setw(6)<<"TAX"<<setw(9)<<"NET PAY"<<endl<<endl;
                   for (i=0; i<counter; i++){
cout<<setw(14)<<empid[i]<<setw(16)<<fname[i]<<setw(17)<<lastname[i]<<setw(4)
<<hw[i]<<setw(5)<<hr[i]<<setw(6)<<gp[i]<<setw(6)<<taxamt[i]<<setw(9)<<np[i]<<endl;
}// FOR
return 0;
}//MAIN

#include <iostream>
#include <iomanip>

using namespace std;

struct Employee {
    char empid[12];
    char fname[14];
    char lastname[15];
    int hw;
    double gp, np, hr, taxrate, taxamt;
};

int readEmployees(Employee *emps) {
    int counter = 0;
    cout << "ENTER EMP ID, FNAME, LNAME, HRS WORKED, HRLY RATE ctrl z to end" << endl;
    while( cin >> emps[counter].empid >> emps[counter].fname >> emps[counter].lastname >> emps[counter].hw >> emps[counter].hr)
        counter=counter+1;
    return counter;
}

void calculateValues(Employee *emps, int counter) {
    for (int i=0; i<counter; i++){
        emps[i].gp = emps[i].hw * emps[i].hr;
        
        if (emps[i].gp > 500) emps[i].taxrate = .30;
        else if (emps[i].gp > 200) emps[i].taxrate=.20;
        else emps[i].taxrate = .10;

        emps[i].taxamt = emps[i].gp * emps[i].taxrate;
        emps[i].np = emps[i].gp - emps[i].taxamt;
    }    
}

void printDetails(Employee *emps, int counter) {
    cout<<endl;
    cout<<setw(14)<<"EMPLOYEE ID"<<setw(16)<<"FIRST NAME"<<setw(17)
    <<"LAST NAME" <<setw(4)<<"HW"<<setw(5)<<"HR"<<setw(6)
    <<"GROSS"<<setw(6)<<"TAX"<<setw(9)<<"NET PAY"<<endl<<endl;
    for (int i=0; i<counter; i++){
        cout<<setw(14)<<emps[i].empid<<setw(16)<<emps[i].fname<<setw(17)<<emps[i].lastname<<setw(4)
        <<emps[i].hw<<setw(5)<<emps[i].hr<<setw(6)<<emps[i].gp<<setw(6)<<emps[i].taxamt<<setw(9)<<emps[i].np<<endl;
    }
}

int main(){
    Employee employees[100];
    int counter = readEmployees(employees);
    calculateValues(employees, counter);
    printDetails(employees, counter);
    return 0;
