Here is the scenario we want to test:
– Write a “if else” statement that checks to see if bx and by are INSIDE the box. If the point (bx,by) is inside the box, print “Inside” otherwise print “Not inside”. (Hint use && in your answer)
– Write a “if else” statement that checks to see if bx and by are OUTSIDE the box. If the point (bx, by) is outside the box, print “Outside” otherwise print “Not outside”. (Hint use && in your answer)
– Test your IF statements with different values of bx and by
– See if you can make these if statements do the opposite by using the ! (not)
Values for the points:
x1,y1 = 100,100
x2, y2 = 120,150
bx, by = 115, 120
Here’s my solutions for it:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace lab4
{
class Program
{
static void Main(string[] args)
{
Console.Title = "The Console - Lab 4 - IF statements";
bool returnTrue;
bool notInside;
float x1, y1, x2, y2, bx, by, cx, cy, dx, dy;
x1 = 100;
y1 = 100;
x2 = 120;
y2 = 150;
bx = 115;
by = 120;
cx = 50;
cy = 300;
dx = 115;
dy = 120;
if (bx > x1 && bx < x2 && by > y1 && by < y2)
{
returnTrue = true;
Console.WriteLine("Is bx,by inside the box = " + returnTrue);
}
else
{
returnTrue = false;
Console.WriteLine("Is bx,by inside the box = " + returnTrue);
}
if (cx < x1 || cx > x2 || cy < y1 || cy > y2)
{
returnTrue = true;
Console.WriteLine("Is cx,cy outside the box = " + returnTrue);
}
else
{
returnTrue = false;
Console.WriteLine("Is cx,cy outside the box = " + returnTrue);
}
Console.WriteLine();
if (dx > x1 && dx < x2 && dy > y1 && dy < y2)
{
returnTrue = true;
notInside = !returnTrue;
Console.WriteLine("Is dx,dy inside the box = " + returnTrue);
Console.WriteLine("Is dx,dy inside the box (not operator test) = " + notInside);
}
else
{
returnTrue = false;
Console.WriteLine("Is bx,by inside the box = " + returnTrue);
}
Console.ReadKey();
}
}
}
