Question

I would like to sort a vector

vector<myClass> object;

Where myclass contains many int variables. How can I sort my vector on any specific data variable of myClass.

Answer 1

Overload less than operator, then sort. This is an example I found off the web…

class MyData
{
public:
  int m_iData;
  string m_strSomeOtherData;
  bool operator<(const MyData &rhs) const { return m_iData < rhs.m_iData; }
};

std::sort(myvector.begin(), myvector.end());
