I have a 3x3 matrix grid. If a user on particular cell, how can I identify the cell cordinates after click? Please advise. thanks PJ Assuming you're designing a tic-tac-toe style game, and the grid in question is the standard WPF Grid, I'd imagine you'd be best putting a control in each separate cell. That way you can hook into mouse events for each, like so: <Window x:Class="WpfApplication1.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Window1" Height="300" Width="300"> <Grid ShowGridLines="True"> <Grid

Leetcode: Robot Room Cleaner

由 大城市里の小女人 提交于 2019-12-01 06:40:26
Given a robot cleaner in a room modeled as a grid. Each cell in the grid can be empty or blocked. The robot cleaner with 4 given APIs can move forward, turn left or turn right. Each turn it made is 90 degrees. When it tries to move into a blocked cell, its bumper sensor detects the obstacle and it stays on the current cell. Design an algorithm to clean the entire room using only the 4 given APIs shown below. interface Robot { // returns true if next cell is open and robot moves into the cell. // returns false if next cell is obstacle and robot stays on the current cell. boolean move(); //

'comparison is always true due to limited range of data type' warning in C?

I have the following code //Point.h #define WIDTH 8 #define HEIGHT 8 typedef struct Point { char x; char y; } Point; //Board.c #include <stdbool.h> // Some other functions that we don't care about... bool inBounds(Point * p) { return p->x >= 0 && p->x <= WIDTH && p->y >= 0 && p->y <= HEIGHT; } When I compile this (ppu-gcc 4.1.1), I get the following warning warning: comparison is always true due to limited range of data type even though the range of char is -127 to 127 and WIDTH is 8, which is well inside the range of a char. I've already tried an explicit cast of WIDTH to a char, but still
