    some easy help needed

    Ok, suppose two teams are playing a game against each other, and the winner will advance to the next round. I have to randomly choose one out of two teams chosen, based on their rank out of 16, to advance. How would I do this using RandGen? The team ranked 1 will play 16, rank 2 plays 15, rank 3 plays 14... etc.

    and for the rank 1 against rank 16 game, the odds are in rank 1's favor, except there is sitll a chance of rank 16 winning.

    thanks a lot for help.

    [code]

    int t1,t2;

    t1=random(17);
    t1=t1+1;

    re:
    t2=random(17);
    t2=t2+1;
    if(t2==t1)
    goto re;

    if(winner==0)
    cout<<"TEAM "<<t1<<" chosen";
    if(winner==1)
    cout<<"TEAM "<<t2<<" chosen";

    [\code]

    not tested program/code

    random() = stdlib.h

    random(17) = randomely selects any num from 0 to 16, that's why i added 1 to t1,t2

    if you don't want goto [nobody likes it] use do-while. it's better but goto is simple.

    this is the code my teacher gave us to look at.
    it doesn't go up to the final four or the semifinals.
    #include<iostream.h>
    #include<fstream.h>
    #include"RandGen.cpp"
    #include"apvector.h"
    #include"apstring.cpp"
    #include<stdlib.h>
    struct region
    {
    apstring name;
    apvector<apstring>teams;
    };
    void main()
    //East Midwest South West
    {
    apvector<region>bracket(4);
    ifstream infile;
    infile.open("bracket.dat",ios::in);
    for(int i=0; i<4; i++)
    {
    bracket[i].teams.resize(17);
    getline(infile, bracket[i].name);
    for(int j = 1; j <=16; j++ )
    {
    getline(infile, bracket[i].teams[j]);
    }
    }
    RandGen n;
    // games in a region
    for( i = 0; i<4; i++ )
    {
    cout<<bracket[i].name<<" Region\n";
    for(int j=1; j<=8; j++)
    {
    int t = n.RandInt(1,17);
    cout<<"Game "<< j << endl;
    cout<<bracket[i].teams[j]
    <<" vs. "
    <<bracket[i].teams[17-j]
    <<endl;

    cout<<"Winner is ";
    if(j < 17 - t)
    cout << bracket[i].teams[j] << endl;
    else
    cout << bracket [i].teams[17-j] << endl;

    }
    cin.get();// creates a pause between brackets
    system("cls");// clear the screen
    }

    }


    //end code

    ok i dont get the ........


    cout<<"Winner is ";
    if(j < 17 - t)
    cout << bracket[i].teams[j] << endl;
    else
    cout << bracket [i].teams[17-j] << endl;


    ........ part of that
