sort vector of objects c++ code example

Example 1: sort vector struct c++

struct data{
    string word;
    int number;
};


bool my_cmp(const data& a, const data& b)
{
    // smallest comes first
    return a.number < b.number;
}

std::sort(A.begin(), A.end(), my_cmp);

Example 2: sorting a vector of objects c++

#include <vector>
#include <algorithm>

using namespace std;

vector< MyStruct > values;

sort( values.begin( ), values.end( ), [ ]( const MyStruct& lhs, const MyStruct& rhs )
{
   return lhs.key < rhs.key;
});
