Thread: String Array Shuffle

Alright so this my code for the shuffle so far. I am making a team randomizer with a max of 250 teams and it is 4 players per team.

Code:

	
srand ( time(NULL) );
for(i=0;i<(Teams*4);i++)
{
	int random = rand() % (Teams * 4);
	strcpy(temp.x[0].name, player.x[i].name);
	strcpy(player.x[i].name, player.x[random].name);
	strcpy(player.x[random].name, temp.x[0].name);
}

for(i=0;i<Teams;i++)
{
	printf("-------------\nTeam %d\n--------------\n %s \n %s \n %s \n %s \n", i+1,player.x[i].name, player.x[i+1].name, player.x[i+2].name, player.x[i+3].name);
}

It shuffles good and all that, the only problem is that a player may be put down on the same team twice. I have been searching and searching and well being new, I have tried everything i can think of. So, any pointers

What do you mean? I know what the code above does is random all the strings in the array, but i need it so that one string does not get randomized and put in two different locations. I dont know if i am explaining this right so.

ex.

array[0] gets randomized to array[8] , but i dont want it to also get randomized with say array[10] because when you print out the list, a name that was entered will be gone and two of the same name will appear.
