Rectangle

Instructions

Consider that a point is defined by its coordinates and that a rectangle is defined by the points of the upper left and lower right corners.

  • Define two structures named, point and rectangle.

  • The struct point has to have two variables, x and y, type int.

  • The struct rectangle has to have two variables, upLeft and downRight type point.

  • The goal is to make a program that:

    • Given a slice of points of size n returns the smallest rectangle that contains all the points in the vector of points. The name of that function is defineRectangle.
    • And which calculates and prints the area of that rectangle you define.

Expected main and function for the program

func defineRectangle(ptr *point, n int) *rectangle {

}

func calArea(ptr *rectangle) int {

}

func main() {
	vPoint := []point{}
	rectangle := &rectangle{}
	n := 7

	for i := 0; i < n; i++ {
		val := point{
			x: i%2 + 1,
			y: i + 2,
		}
		vPoint = append(vPoint, val)
	}
	rectangle = defineRectangle(vPoint, n)
	fmt.Println("area of the rectangle:", calArea(rectangle))
}

Expected output

student@ubuntu:~/[[ROOT]]/test$ go build
student@ubuntu:~/[[ROOT]]/test$ ./test
area of the rectangle: 6
