int main()

 srand(time(NULL));
 int array[4];
 array[0]=rand() % 3 + 0;  
 for(int i=1;i<=3;i++)
 {
    array[i]=rand() % 3 + 0;
    if ((array[i]=array[i-1])||(array[i]=array[i-2])||(array[i]   =array[i-3]))
   {
           array[i]=rand() % 3 + 0;
   }
 }
 cout<<array[0]<<array[1]<<array[2]<<array[3]<<endl;
 system("pause");
 return 0;
}

 int array[4];
 array[0]=rand() % 3 + 0;

if ((array[i]=array[i-1])||(array[i]=array[i-2])||(array[i] =array[i-3]))

You probably want to use == instead of =. The former is comparison and the latter is assignment. Aside from that, your loop seems to work okay. What exactly are you trying to do?
