Sorting Strings

[Dlockwood]

Hi,I am printing out information and it works successfully, however i wish to print it lexicographically\alphabetically by comparing the last name strings stored into this vector that i am printing. How can I do this.

Here is my code

void printStudent()
{
    system("cls");
    cout << "Records\n-------------------------\n\n";
    
      
    
    //Loops through the vector that stores the student objects
    for(int i = 0; i < students -> size(); i++)
    {
      students -> at(i).print();
    }
    
    system("Pause");
}

You can have the standard sort function do the job for you. Declare & define a function that compares two students:

bool is_less(const Student & s1, const Student & s2)
{
     return s1.m_last_name.compare(s2.m_last_name)<0;
}

And then do the sorting like this:
sort(student_vector.begin(),student_vector.end(),is_less);
