Point::distance(Point &p2)

otherPoint) calculates the Euclidean distance between the current point and the point specified by the otherPoint parameter.

Here's an implementation in Python:

import math

class Point:
    def __init__(self, x, y):
        self.x = x
        self.y = y

    def distance(self, otherPoint):
        dx = self.x - otherPoint.x
        dy = self.y - otherPoint.y
        return math.sqrt(dx**2 + dy**2)

This implementation uses the math module to calculate the square root of the sum of the squared differences between the x and y coordinates of the two points.
