Code:

main()
{
	int i,k,j = 6;
	int a[6];

	while ( getch() == 'C')
	{
		j = 6;
		while (j)
		{
			k = 6-j;
			i = (rand())%47;
			a[k] = i;

			while ( k-- )
			{
				if ( a[k] == i )
				{
					k = 6-j;
					i = (rand())% 47;
					a[k] = i;
				}
			}
			printf(" i = %d\t",i);
			j--;
		}
		printf("\n");
	}
}
