Check if a point lies on or inside a rectangle | Set-2
Given coordinates of bottom-left and top-right corners of a rectangle. Check if a point (x, y) lies inside this rectangle or not.
Examples:
Input: bottom-left: (0, 0), top-right: (10, 8), point: (1, 5)
Output: YesInput: bottom-left: (-1, 4), top-right:(2, 3), point:(0, 4)
Output: No
This problem is already discussed in a previous post. In this post we have discussed a new approach.
Approach: The above problem can be solved by observation. A point lies inside or not the rectangle if and only if it’s x-coordinate lies between the x-coordinate of the given bottom-right and top-left coordinates of the rectangle and y-coordinate lies between the y-coordinate of the given bottom-right and top-left coordinates.
Below is the implementation of the above approach:
C++
// CPP program to Check if a // point lies on or inside a rectangle | Set-2 #include <bits/stdc++.h> 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; } |
