Here's the code from the other posting. In fact, Paul's use of structures works better than the multidimensional array, so I'm going with that ::
#include <algorithm>
#include <vector>
#include <string>
#include <iostream>
struct PersonInfo
{
std::string name;
int age;
int wage;
PersonInfo(const std::string& n, int a, int w) : name(n), age(a), wage(w) { }
};
bool SortByAge(const PersonInfo& first, const PersonInfo& second)
{
if ( first.age < second.age )
return true;
return false;
}
bool SortByWage(const PersonInfo& first, const PersonInfo& second)
{
if ( first.age == second.age )
{
if ( first.wage < second.wage )
return true;
return false;
}
return first.age < second.age;
}
// commented out since names/data will be provided
// std::string NameGenerator()
// {
// static int i = 0;
// ++i;
// std::string sName = "Joe";
// return sName += (char)(i + '0');
// }
void SortByAgeWage(std::vector<PersonInfo>& info)
{
// first sort by age
std::sort(info.begin(), info.end(), SortByAge);
// sort by wage given that the array has been sorted by age
std::sort(info.begin(), info.end(), SortByWage);
}
int main()
{
std::vector<PersonInfo> theInfo;
theInfo.push_back(Tim, 12, 33);
theInfo.push_back(Mark, 34, 28);
theInfo.push_back(Tom, 21, 30);
theInfo.push_back(Cliff, 13, 33);
theInfo.push_back(Vini, 17, 28);
theInfo.push_back(Matt, 10, 28);
theInfo.push_back(Ben, 9, 29);
theInfo.push_back(Brandon, 15, 14);
// removed this since I supplied the data to be used -- theInfo.push_back(PersonInfo(NameGenerator(), 7, 1));
//...
int i;
std::cout << "Sorted by Age + Wage\n\n";
std::cout << "Name Age Wage Ranking\n";
std::cout << "===== ==== ==== =======\n";
SortByAgeWage(theInfo);
for ( i = 0; i < theInfo.size(); ++i )
std::cout << theInfo[i].name << " "
<< theInfo[i].age << " " << theInfo[i].wage << "\n";
// Somehow here the cout makes it to a GUI App in Windows ??
