For Loop and Creating Averages

[rossjohn07]

If I want to make program that calculates the averages I have a problem with the averaging part. If I have 5 different people on each team and there are three teams how would I average the score of the three teams as well individually average each player.

Part of my code looks like this:

for(PLAYER=1; PLAYER <=5; PLAYER++)
{
count++;


cout<<"Please enter the score of player <<PLAYER<<":\n";
cin>>score1;


cout<<"Please enter the score of player <<PLAYER<<":\n";
cin>>score2;

cout<<"Please enter the score of player <<PLAYER<<":\n";
cin>>score3;

} 

When I enter the scores in an calculate the average for each player it averages the same amount for each player.

You can try this for the above code and you will have to modify the varibles and other stuff

for(i=1; i <=5; ++)
{
count++;



cout<<"Please enter the scores of player  <<PLAYER[i]<<":\n";
cin>>score1;


cout<<"Please enter the score of player <<PLAYER[i]<<":\n";
cin>>score2;

cout<<"Please enter the score of player <<PLAYER[i]<<":\n";
cin>>score3;

totalscore =score1+score2+score3;
teamscore[i]=score1+score2+score3;
score1=0;
score2=0;
score3=0;


}  

this would mean you have to have arrays for the team scores and the player scores this should give you a start

[rossjohn07]

Is there any way to store these values without out using arrays. Or do I have to create separate way of calculating the averages with separate statements and for statements.

bear in mind that if you declare you are using namespace std; like I assume you are as you aren't using std::cout << etc then you cannot use 'count' as a variable as there is already something in the std namespace called count.

let me try to understand this better:

1. you have 3 teams with 5 players you need to have averages for each player, each team d total avg. for all teams

the for loop you have need to include a variable to increment the total team score

a variable to calculate the aver of each player each of the 5 times you go through the for loop

2. first for loop will need to be for(team=1,team ,team <=3,team++)

in that for loop will be the for(PLAYER=1,PLAYER<=5,PLAYER++)
and calculate that players average and add the scores to the team score variable.

3. before going to the next team you need to calculate that current teams average

for team=1,team<=3,team++)
{
    for(i=1; i <=5; ++)
{
count++;



cout<<"Please enter the scores of player  <<PLAYER[i]<<":\n";
cin>>score1;


cout<<"Please enter the score of player <<PLAYER[i]<<":\n";
cin>>score2;

cout<<"Please enter the score of player <<PLAYER[i]<<":\n";
cin>>score3;

totalscore =score1+score2+score3;
teamavg=(score1+score2+score3)/3;
score1=0;
score2=0;
score3=0;

   }  
totalavg=totalscore/15;
}    

somewhere in there you will need to print the avgs. out but i think storing the teams scores and players scores in two arrays would be your best bet then you can use use for loops to print out a nice report of the teams avg and players for each team avgs. at the end of the program
i hope this helps you out

	double totalTeamScores[5];

	for ( int team = 0; team < maxTeam; team++ )
	{
		totalTeamScores[ team ] = 0;
		cout << "Team no. " << team ;

		for ( int player = 0; player < maxPlayer; player++ )
		{
			cout << " - Player no. " << player << endl;
			cin >> score[ team ][ player ];
			totalTeamScores[ team ] += score[ team ][ player ];
			totalAllScores += score[ team ][ player ];

	for ( int team = 0; team < maxTeam; team++ )
	{
		cout << "Average for team " << team << " points " << totalTeamScores[ team ] / maxPlayer << endl;
	}

	cout << "Average all teams " << totalAllScores / ( maxPlayer * maxTeam ) << endl;

	return 0;
