Question

this imp is using vector

void addStudent(student g)
   {
      
       for(unsigned int i =0; i<newStudent.size(); i++)
        {
            if(newStudent[i]== nullptr)
            {
                newStudent[i] =g;
                break;
            }
        }
   }

private:

std::vector<student> newSudent;

if you wanted to change it to std::map would this be the way to change it

void addStudent(std::string name, student g)
{
    newStudent.insert(std::make_pair(name,g));

}

private:

std::map<std::string, student> newSudent;

need help.

Explanation / Answer

As we have a vector of pairs
name of the student is the key and student object will be the value in the map as
pair has first element as student name and second element as student object

so can copy the data from vector to a map with an insert iterator

Here goes the same code i am populating 3 student pairs into the vector

Hope this hepls you

std::vector<std::pair<std::string, int> > studentVector;

// here g means student object

studentVector.push_back(std::make_pair("Tom", g));
studentVector.push_back(std::make_pair("Allen", g));
studentVector.push_back(std::make_pair("Elf", g));

std::map<std::string, student> mapped_studentVector;

std::copy(studentVector.begin(), studentVector.end(),
std::inserter(mapped_studentVector, mapped_studentVector.begin()));

or you can straight away initialize the map like this

std::map<std::string, student> mapped_studentVector((studentVector.begin()), studentVector.end());
