Compare Heights

[VANDEMAN]

I'm having a problem with getting my program to compare the vaulters heights.
I know I need else if statements, but were do I go from there.

Thanks a bunch.

#include <iostream>
#include <iomanip>

using namespace std;

int main()
{
    char vaulter[99];
    double vheight1, vheight2, vheight3;
    double date1, date2, date3;

    // This is were you input the NAME, HEIGHT, and DATE of the vaulter.

          cout << "What is the name of the pole vaulter.\n" ;
          cin >> vaulter;

          cout << "What is the FIRST height & date: " << endl;
          cin >> vheight1;
          cin >> date1;

          cout << "What is the SECOND height & date: " << endl;
          cin >> vheight2;
          cin >> date2;

          cout << "What is the THIRD height & date: " << endl;
          cin >> vheight3;
          cin >> date3;

          if (vheight1 > vheight2 && vheight1 > vheight3)
            {
            }
                else if (vheight1 < vheight2 && vheight1 < vheight3)


          if (vheight2 > vheight1 && vheight2 > vheight3)
            {
            }
                else if (vheight2 < vheight1 && vheight2 < vheight3)


          if (vheight3 > vheight1 && vheight3 > vheight2)
            {
            }
               else if (vheight3 < vheight1 && vheight3 < vheight2)


          if (vheight1 && vheight2 && vheight3 <= 2.0 || vheight1 && vheight2 && vheight3 >= 5.0)
            {
            }
                cout << "You need a number between 2.0 and 5.0.\n";


         cout << "-----------------------\n";
         cout << "Name: " << vaulter << endl;
         cout << setprecision(1) << fixed << "1st: " << vheight1 << vheight2 << vheight3 << "On " << date1 << date2 << date3 << endl;
         cout << setprecision(1) << fixed << "2nd: " << vheight1 << vheight2 << vheight3 << "On " << date1 << date2 << date3 << endl;
         cout << setprecision(1) << fixed << "3rd: " << vheight1 << vheight2 << vheight3 << "On " << date1 << date2 << date3 << endl;
    return 0;
}
