I have to calculate the wage for each employee. How would I write a function to do this?
And how would I sort the employees according to their wage?
The data file looks like this: I think I have to convert int to string or the other way around. I know that The function for calculating wage is wrong. Thanks.

and this is my code that I am trying to write:
#include <iostream>
#include <fstream>
#include <string>
#include <sstream>
#include <stdlib.h>
using namespace std;
struct Record
{
string name;
int id;
double rate;
int hrWorked;
double wage;
};
void read_file(string[], int);
void calculate_wage(Record& payroll);
int main()
{
int e = 5;
Record payroll[5];
string s[5];
cout << "Your entered file is: " << endl;
read_file(s, e);
calculate_wage(payroll);
system("pause");
return 0;
}
void read_file(string s[], int e)
{
ifstream myFile;
myFile.open("Project 3.dat");
string str;
int i = 0;
if (myFile.is_open())
{
while (getline(myFile, str))
{
s[i++] = str;
cout << str << endl;
}
myFile.close();
}
else
{
cout << "No Data Found!" << endl;
}
}
void calculate_wage (Record& payroll) // i know this part isnt right but im not sure what to do for this
{
char emplresult[256]; // need to convert int to string
payroll.wage = atoi(emplresult);
payroll.rate = atoi(emplresult);
payroll.hrWorked = atoi(emplresult);
for (int i = 0; i < 5; i++)
{
payroll[i].wage = payroll[i].rate * payroll[i].hrWorked;
}
}

use std algorithms, it will make your code readable and maintainable. For example you can sort your objects with std::sort:
#include <string>
#include <vector>
#include <algorithm>
#include <iostream>
struct Record
{
Record(std::string name, double wage) : name(name), wage(wage) {};
std::string name;
int id;
double rate;
int hrWorked;
double wage;
};
int main() {
using Records = std::vector<Record>;
Records records;
records.push_back(Record("Pedro",20));
records.push_back(Record("Andres",10));
records.push_back(Record("Santiago",15));
std::sort(records.begin(),records.end(),
[](auto& lhs, auto& rhs) {
return lhs.wage < rhs.wage;
});
for (const auto& r : records) {
std::cout << "Name: " << r.name << " wage: " << r.wage << "\n";
}
}
which outputs the sorted records:
Name: Andres wage: 10
Name: Santiago wage: 15
Name: Pedro wage: 20
I hope this gives you inspiration for your code!
