The funny thing is that this was an answer! The problem I have is this: I have a Person class, which is initialized with a string, and it splits into a number and another string. After the class is mounted, I get an entire file and split it into several strings, which will create multiple variables (objects). They should be drawn by number, and show everything on the screen. I mounted the program but it shows nothing! My code is:
#include <iostream> //cout - main
#include <string> //string - main ,class and func
#include <algorithm> //reverse, sort, greater - class
#include <vector> //vector - main and func
#include <sstream> //stringstream - main
using namespace std;
class Person
{
private:
string name_;
unsigned num_;
public:
Person(string raw)
{
this->num_ = stoi(raw);
reverse(raw.begin(), raw.end()); //Those "reverse" are for getting only the number and the string
raw = raw.substr(0, raw.find(' '));
reverse(raw.begin(), raw.end()); //Ends here :P
this->name_ = raw;
}
string name() {return this->name_;}
unsigned num() {return this->num_;}
};
vector<Person> order_vector(vector<Person>& rawPerson)
{
//Ok, lets check which one is the first
vector<Person> ret;
vector<unsigned> values;
for(unsigned i = 0; i < rawPerson.size(); i++) values.push_back(rawPerson[i].num());
sort(values.begin(), values.end(), greater<unsigned>());
for(unsigned a = 0; a < rawPerson.size(); a++)
for(unsigned i = 0; i < rawPerson.size(); i++)
{
if(a == rawPerson[i].num()) ret.push_back(rawPerson[i]);
}
return ret;
}
int main()
{
string raw_strings;
vector<Person> rawPerson;
vector<Person> ordened_Person;
stringstream rawstring(string("10 tennent\n9 Eccleston\n12 Capaldi\n11 Smith"));
while(getline(rawstring, raw_strings)) //get info before '\n'
{
if(!raw_strings.empty()) //If it is not an '\n'
{
rawPerson.push_back(Person(raw_strings)); // add an object
}
}
ordened_Person = order_vector(rawPerson);
for(auto& a : ordened_Person) std::cout << a.num() << '\t' << a.name() << std::endl;
}
I believe the error is in returning the ordered vector, which is most likely. What am I doing wrong?
