Sorting arrays next to other arrays which are the same

[justasrod]

I just wrote a program where program sorts people by time(minutes).But what and where should I add a code, if minutes are the same and I need to sort seconds as well

#include <iostream>
#include <algorithm>
#include <string>
using namespace std;

struct people{
string name;
int min;
int sec;
};
bool comp(const people &p1, const people &p2) {return (p1.min < p2.min); }

int main()
{
 int temp;
people z[6];
for(int i=0; i<6; i++)
    {
   cin>>z[i].name;
   cin>>z[i].min;
   cin>>z[i].sec;
 }
 sort(z, z + 6,comp);
cout<<endl;

for(int i=0; i<6; i++)
    {
    cout<<z[i].name<<" "<<z[i].min<<" "<<z[i].sec<<endl;
 }
    return 0;
}

/* input for example:
John 19 15  
Liza 9 59 
Michael 19 45 
Kira 2 37 
Thomas 5 41 
Justas 19 24

bool comp(const people &p1, const people &p2) {
    return p1.min == p2.min ? p1.sec < p2.sec : p1.min < p2.min;
}
