Instead of using all those variables try using two dimensional array:
int array[6][6];

to check for vertical column just scan each column in the loop like that:
for (j=0; j<6; j++) {
for (i=0; i<4; i++) {
   if (array[j][i] == array[j][i+1] && array[j][i+1] == array[j][i+2])
	then you have a column with 3 same things
}
}
you can do similar thing with rows. For diagonal you rows you can just
easily modify it to make it work.
