help needed for my connect four programme.
hi there. katy here. I am doing a "Connect 4" program for my assignment and i've done the main part, which I should not change (my lecturer told me not to). .can anyone help me to convert this function below to suit my program??i need my program to have a verticalwin/horizontalwin and a diagonalwin function. and also when all the tiles is full,i want my program to give an output such as "the game is a tie".please help me.i'm new here.so forgive me if i'm wrong.
the function that i need modified is:
Code:
bool check(int a, int b)
{
int vertical = 1;//(|)
int horizontal = 1;//(-)
int diagonal1 = 1;//(\)
int diagonal2 = 1;//(/)
char player = place[a][b];
int i;//vertical
int ii;//horizontal
//check for vertical(|)
for(i = a +1;place[i][b] == player && i <= 5;i++,vertical++);//Check down
for(i = a -1;place[i][b] == player && i >= 0;i--,vertical++);//Check up
if(vertical >= 4)return true;
//check for horizontal(-)
for(ii = b -1;place[a][ii] == player && ii >= 0;ii--,horizontal++);//Check left
for(ii = b +1;place[a][ii] == player && ii <= 6;ii++,horizontal++);//Check right
if(horizontal >= 4) return true;
//check for diagonal 1 (\)
for(i = a -1, ii= b -1;place[i][ii] == player && i>=0 && ii >=0; diagonal1 ++, i --, ii --);//up and left
for(i = a +1, ii = b+1;place[i][ii] == player && i<=5 && ii <=6;diagonal1 ++, i ++, ii ++);//down and right
if(diagonal1 >= 4) return true;
//check for diagonal 2(/)
for(i = a -1, ii= b +1;place[i][ii] == player && i>=0 && ii <= 6; diagonal2 ++, i --, ii ++);//up and right
for(i = a +1, ii= b -1;place[i][ii] == player && i<=5 && ii >=0; diagonal2 ++, i ++, ii --);//up and left
if(diagonal2 >= 4) return true;
return false;
}
i need it to suit my current programme.please help.
