Problems with a sort function :void SortAge(); calling the function to print an employee name : void print(int d), I only recive the name of the first employee i had pushed into the Stack... I don t have any sintax error thank for time

#include <iostream>
#include <cstdio>

using namespace std;
struct employee
{
string name;
int age;

};


class Stack
{
employee employeeList[1000];

int pos =-1;

public:

void push(employee e)
{
    pos++;
    employeeList[pos] = e;


}
employee pop(int n)
{
    employee e;
    if(n<= pos && pos >= 0 && n >=0)
    {

        e= employeeList[pos] ;
        for(int j =n; j < pos; j++ )
        {
            employeeList[pos] = employeeList[pos + 1];

        }

        pos--;
    }
    return e;
}

void print(int d)
{
    if(d > pos || d <0 || pos < 0)
    {
        cout<< "Error";

    }
    cout<<employeeList[d].name<<endl;
}

char menu()
{

    char choice;
    cout << "Press 1. to push an employee"<<endl;
    cout << "Press 2. to pop an employee"<<endl;
    cout << "Press 3. to show an employee"<<endl;
    cout << "Press 4. to sort the list by age"<<endl;
    cin>> choice;

    return choice;


}
void SortAge()
{
    int j;
    for(j = 0;j < pos ; j++)
    {
        if(employeeList[j].age >employeeList[j+1].age)
        {
            employee e;
            e = employeeList[j];
            employeeList[j+1] = employeeList[j];
            employeeList[j] = e;
            j = 0;
        } continue;
    }

}
