给定矩形左下角和右上角的坐标。检查点(x，y)是否位于此矩形内。
例子：

在上一篇文章中已经讨论了这个问题。在这篇文章中，我们讨论了一种新方法。
方法：以上问题可以通过观察解决。当且仅当它的x坐标位于给定矩形的右下角和左上角坐标的x坐标之间并且y坐标位于给定的下半角的y坐标之间时，点才位于矩形的内部或不位于矩形的内部-右和左上角坐标。
下面是上述方法的实现：

C++
// CPP program to Check if a
// point lies on or inside a rectangle | Set-2
#include 
using namespace std;
 
// function to find if given point
// lies inside a given rectangle or not.
bool FindPoint(int x1, int y1, int x2,
               int y2, int x, int y)
{
    if (x > x1 and x < x2 and y > y1 and y < y2)
        return true;
 
    return false;
}
 
// Driver code
int main()
{
    // bottom-left and top-right
    // corners of rectangle
    int x1 = 0, y1 = 0, x2 = 10, y2 = 8;
 
    // given point
    int x = 1, y = 5;
 
    // function call
    if (FindPoint(x1, y1, x2, y2, x, y))
        cout << "Yes";
    else
        cout << "No";
 
    return 0;
}

Java
// Java program to Check if
// a point lies on or inside
// a rectangle | Set-2
class GFG
{
 
// function to find if given point
// lies inside a given rectangle or not.
static boolean FindPoint(int x1, int y1, int x2,
                         int y2, int x, int y)
{
if (x > x1 && x < x2 &&
    y > y1 && y < y2)
    return true;
 
return false;
}
 
// Driver code
public static void main(String[] args)
{
     
    // bottom-left and top-right
    // corners of rectangle
    int x1 = 0, y1 = 0,
        x2 = 10, y2 = 8;
 
    // given point
    int x = 1, y = 5;
 
    // function call
    if (FindPoint(x1, y1, x2, y2, x, y))
        System.out.println("Yes");
    else
        System.out.println("No");
}
}
