I'm working on a project called treasure hunt game board, where we have to make a 10x10 2d array and there will be 5 treasures and 5 pirates. Whenever the player encounters a treasure, they gain 100, then if they encounter the second one, they gain another 200, and so on. But if they encounter a pirate they lose 100. It should display the total of gold they have each time.

What I have tried:

if(board[x][y] == 'T')
{
    treasureCount++;
    doubloons = doubloons + (treasureCount * 100);
}
else if(board[x][y] == 'P')
{
    pirateCount++;
    doubloons = doubloons - (pirateCount * 100);
}
else if(board[x][y] == 'B')
{
    treasureCount++;
    pirateCount++;
    doubloons = doubloons + (treasureCount * 50);
}
else if(board[x][y] == 'X')
{
