C++ homework assistance bubble and selection sort with structures
My lab assignment is to sort an array of structures that contains employee data and sort them using bubble and selection sort functions. It writes the data to an output file. The code that i wrote only sorts the employee ID numbers, the name and city of the employee remain in the same order. My lab instructor said that the name and city have to be joined with the ID number, but i dont have a clue as to how to do that. I have made many attempts to try to get this to work but i receive errors such as "invalid conversion from char to const char when i try to strcat the name and city to the ID variable. Any assistance would be helpful.
Code:
#include<iostream>
#include<fstream>
#include<iomanip>
#include<cstring>
using namespace std;
// Needed for sufficient size for arrays
const int Name_Length = 15;
const int City_Length = 15;
// Structure declared to store employee data
struct EmployeeInfo
{
int EmployeeID;//will store employee's IDs
char EmployeeName[Name_Length];// will store employee's names
char City[City_Length];// will store employee's city
};
void OpenOutputFile (ofstream&, char[]);
void PrintHeading (ofstream&);
void showArray(ofstream&,EmployeeInfo [], int);// displays original unsorted data
void BubbleSortArray(EmployeeInfo [], int);// bubblesorts the data
void selectionSortArray(EmployeeInfo [], int);//selectionsorts the data
int main()
{
char variable;
const int Num_Workers = 50;
//Initialized the employee structure with employee data
EmployeeInfo Employees[Num_Workers] = {
