Search functions not returning proper values

[Tubes]

Part of my assignment requires making a search function to find employees in a database. I got the function that searches by id (a five character string of digits) to work, but I can't seem to get the one that goes by last name to work. It returns no results, and in a delete function used later, deletes chunks at random without reference to what is put in. Could anyone shed some light on what's going wrong?

The problem function:

void nameSearch(Employee db[],int nEmployees){
     char choice[13];
     cin.get();
     cout << "Enter search value: ";
     cin.getline(choice,13);
     cout << "No. EmpID Employee Name        Email                Salary" << endl;
     cout << "--- ----- -------------------- -------------------- ----------" << endl;
     for (int count = 0; count<nEmployees; count++){
         if (strcmp(db[count].lastName,choice)==0) {
            cout.setf(ios::fixed | ios::showpoint);
            cout.precision(2);
            cout << setw(3) << count + 1 << " " << setw(5) << db[count].id << " " << setw(10) << db[count].firstName << " " << db[count].lastName
                 << setw(24) << db[count].email << " " << setw(10) << db[count].salary << endl;
         }
}
return;
}

The function that searches by id, which works:

void idSearch(Employee db[],int nEmployees){
     char choice[6];
     cin.get();
     cout << "Enter search value: ";
     cin.getline(choice,6);
     cout << "No. EmpID Employee Name        Email                Salary" << endl;
     cout << "--- ----- -------------------- -------------------- ----------" << endl;
     for (int count = 0; count<nEmployees; count++){
         if (strcmp(db[count].id,choice)==0) {
            cout.setf(ios::fixed | ios::showpoint);
            cout.precision(2);
            cout << setw(3) << count + 1 << " " << setw(5) << db[count].id << " " << setw(10) << db[count].firstName << " " << db[count].lastName
                 << setw(24) << db[count].email << " " << setw(10) << db[count].salary << endl;
         }
}
return;
}

We would need more information. If this were my program, I would this before line 9 at your function.
cout << db[count].lastName << '\n';

If I were to hazard a guess, it looks like you're asking for a full name, but then only comparing the last name.

[Tubes]

It was my intent to only ask for the last name. I'm just trying to figure out why the second function works as intended and the first one doesn't, when they look functionally identically. My guess would be it's some kind of buffer problem, as the "id" in the first one is always 5 digits long and the names are of variable length, but I have no idea what i would need to fiddle with.

Here's the full program:

#include <iostream>
#include <cstdlib>
#include <cstring>
#include <iomanip>
#include <string>
#define byID 1
#define byNAME 2
#define dbSIZE 100
#define idSIZE 5
#define nameSIZE 12
#define emailSIZE 20
using namespace std;
struct Employee{
       char id[idSIZE + 1];
       char firstName[nameSIZE + 1];
       char lastName[nameSIZE + 1];
       char email[emailSIZE + 1];
       double salary;
};

void createRecord(char *id, char *firstName, char *lastName, char *email, double salary, Employee db[], int &nEmployees);

void output(Employee db[], int nEmployees) {
     cout.setf(ios::fixed | ios::showpoint);
     cout.precision(2);
     cout << "No. EmpID Employee Name        Email                Salary" << endl;
     cout << "--- ----- -------------------- -------------------- ----------" << endl;
     for (int count = 0; count<nEmployees; count++){
         cout << setw(3) << count + 1 << " " << setw(5) << db[count].id << " " << setw(10) << db[count].firstName << " " << db[count].lastName
              << setw(24) << db[count].email << " " << setw(10) << db[count].salary << endl;
         }

You aren't calling nameSearch in main(). I didn't read passed that. Doesn't look like a buffer problem, though you should make sure the const char*s passed to create record are the within the length. Your program would break otherwise.

You have those defines at the top of the file, you should use them everywhere (line 126, 144, etc).
