sorting a vector of objects c++ sorting a vector of objects c++ c++ sort vector of objects by property c++ sort vector of objects by property

The solution for “sorting a vector of objects c++ sorting a vector of objects c++ c++ sort vector of objects by property c++ sort vector of objects by property” can be found here. The following code will assist you in solving the problem.

``````#include
#include
using namespace std;
vector< MyStruct > values;
sort( values.begin( ), values.end( ), [ ]( const MyStruct& lhs, const MyStruct& rhs )
{
return lhs.key < rhs.key;
});struct MyStruct
{
int key;
std::string stringValue;

MyStruct(int k, const std::string& s) : key(k), stringValue(s) {}
};

struct less_than_key
{
inline bool operator() (const MyStruct& struct1, const MyStruct& struct2)
{
return (struct1.key < struct2.key);
}
};

std::vector < MyStruct > vec;
vec.push_back(MyStruct(4, “test”));
vec.push_back(MyStruct(3, “a”));
vec.push_back(MyStruct(2, “is”));
vec.push_back(MyStruct(1, “this”));
std::sort(vec.begin(), vec.end(), less_than_key());vector< cat > catSorter::SortCatsByAge(){
vector< cat > cats_copy = cats;
std::sort(cats_copy.begin(), cats_copy.end());
return cats_copy;
}class cat {
public:
int age;
bool operator< (const cat &other) const {
return age < other.age;
}
};``````
