Game of life

[gotit]

Good day! Can you help me with my code regarding the game, GAME OF LIFE. Please try to edit my code cause it keeps on lagging when I run it. Your help would be so much appreciated. Thank you!:)



/*Game of Life*/

Your algorithm goes here. You don't need to modify any other part of the program.

You can use the array temp[][] to store the next generation.
The code below copies the contents of temp[][] back to the array board[][]
before returning.

I'm a newbie to reading C++ code so I can only understand bits your code completely. Can you please tell me with it's suppose to do? (I found the title of your thread interesting :))

Thanks for helping.I'm still figuring out my mistakes though. Thanks:)

I have edited the first one with this but still the 2nd gen produced is wrong.:( help please!

for(i=1;i<BSIZE-1;i++)
for(j=1;j<BSIZE-1;j++){
y=0;
if (board[i-1][j-1]=='x')
y++;
if (board[i][j-1]=='x')
y++;
if (board[i+1][j-1]=='x')
y++;
if (board[i-1][j]=='x')
y++;
if (board[i+1][j]=='x')
y++;
if (board[i-1][j+1]=='x')
y++;
if (board[i][j+1]=='x')
y++;
if (board[i+1][j+1]=='x')
y++;

}


/*forming of 2nd generation*/


for (i=0; i<BSIZE; i++){
for (j=0; j<BSIZE; j++){
if (board[i][j] == ' ' && y == 3 ){
temp[i][j] = 'x';
}
else if (board[i][j] == 'x' && y == 2){
temp[i][j] = 'x';
}
else if (board[i][j] == 'x' && y == 3){
temp[i][j] = 'x';
}
else {
temp[i][j] = ' ';
}
}
}

I really don't get how to go with the edges and we have a deadline for this and I'm really running out of time. but anyway thanks for the help:))
