Struct Example in c++

hey, i want to share an example about using strunct in c++.
this is my code :

#include <iostream.h>
#include <conio.h>

void main()
    {
   struct mahasiswa
       {int nim;
      char nama[30][1];
      int nilai[3];
      int tot;
      };

      int jml;
      mahasiswa mhs[25];
      mahasiswa tmp;
      cout<<"Berapa jumlah mahasiswa : ";
      cin>>jml;

      for(int i=0;i<jml;i++)
      {
          mhs[i].tot=0;
         cout<<"Nim   : ";cin>>mhs[i].nim;
         cout<<"Nama  : ";cin>>mhs[i].nama[i];
         for(int j = 0;j<3;j++)
         {    cout<<"Nilai " <<(j+1)<<" : ";
         cin>>mhs[i].nilai[j];
         mhs[i].tot = mhs[i].tot + mhs[i].nilai[j];
         }
         }
         clrscr();
         for(int i=0;i<jml;i++)
         {
             cout<<"Nim      : "<<mhs[i].nim<<endl;
            cout<<"Nama     : "<<mhs[i].nama[i]<<endl;
            for(int j=0;j<3;j++)
            {
            cout<<"Nilai "<<(j+1)<<"  : "<<mhs[i].nilai[j]<<endl;}
            cout<<"Total    : "<<mhs[i].tot<<endl<<endl;
         }
         getch();
         }
