Mwanzo wa Mahali: Muundaji wa Koordinaiti za Kimataifa
Zalisha koordinaiti za kijiografia za bahati nasibu na uwakilishi wa ramani ya kuona. Vipengele vinajumuisha kitufe cha Kuunda, onyesho la umbizo la decimal, na urahisi wa nakala.

Uwakilishi wa Kitaalamu
Ili kutoa muktadha wa kuona kwa kuratibu zilizozalishwa, tunatekeleza ikoni rahisi ya dunia kwa kutumia SVG. Hapa kuna mfano wa jinsi hii inaweza kufanywa:
SVG hii inaunda dunia rahisi yenye mistari ya latitudo na longitudo, na alama nyekundu ikiwakilisha mahali lililotolewa. Nafasi halisi ya alama inaweza kuhesabiwa kulingana na kuratibu zilizozalishwa.

Mifano
Hapa kuna mifano ya msimbo wa kuzalisha kuratibu za nasibu katika lugha mbalimbali za programu:
1import random
2
3def generate_random_coordinates():
4 latitude = random.uniform(-90, 90)
5 longitude = random.uniform(-180, 180)
6 return latitude, longitude
7
8lat, lon = generate_random_coordinates()
9print(f"{lat:.4f}° {'N' if lat >= 0 else 'S'}, {abs(lon):.4f}° {'E' if lon >= 0 else 'W'}")
101function generateRandomCoordinates() {
2 const latitude = Math.random() * 180 - 90;
3 const longitude = Math.random() * 360 - 180;
4 return { latitude, longitude };
5}
6
7const { latitude, longitude } = generateRandomCoordinates();
8console.log(`${latitude.toFixed(4)}° ${latitude >= 0 ? 'N' : 'S'}, ${Math.abs(longitude).toFixed(4)}° ${longitude >= 0 ? 'E' : 'W'}`);
91import java.util.Random;
2
3public class RandomCoordinateGenerator {
4 public static double[] generateRandomCoordinates() {
5 Random random = new Random();
6 double latitude = random.nextDouble() * 180 - 90;
7 double longitude = random.nextDouble() * 360 - 180;
8 return new double[]{latitude, longitude};
9 }
10
11 public static void main(String[] args) {
12 double[] coordinates = generateRandomCoordinates();
13 System.out.printf("%.4f° %s, %.4f° %s%n",
14 Math.abs(coordinates[0]), coordinates[0] >= 0 ? "N" : "S",
15 Math.abs(coordinates[1]), coordinates[1] >= 0 ? "E" : "W");
16 }
17}
181#include <iostream>

6std::pair<double, double> generateRandomCoordinates() {
7 double latitude = (static_cast<double>(rand()) / RAND_MAX) * 180 - 90;
8 double longitude = (static_cast<double>(rand()) / RAND_MAX) * 360 - 180;

18 return 0;
19}

2 latitude = rand(-90.0..90.0)
3 longitude = rand(-180.0..180.0)
4 [latitude, longitude]
5end

7lat, lon = generate_random_coordinates
8puts format("%.4f° %s, %.4f° %s",
9 lat.abs, lat >= 0 ? 'N' : 'S',
10 lon.abs, lon >= 0 ? 'E' : 'W')
111<?php
2function generateRandomCoordinates() {
3 $latitude = mt_rand(-90 * 10000, 90 * 10000) / 10000;
4 $longitude = mt_rand(-180 * 10000, 180 * 10000) / 10000;
5 return [$latitude, $longitude];
6}
7
8list($lat, $lon) = generateRandomCoordinates();
9printf("%.4f° %s, %.4f° %s\n",
10 abs($lat), $lat >= 0 ? 'N' : 'S',
11 abs($lon), $lon >= 0 ? 'E' : 'W');
12?>
13Utekelezaji wa Kitufe cha Nakala
Ili kutekeleza kazi ya Kitufe cha Nakala, tunaweza kutumia API ya Clipboard. Hapa kuna mfano rahisi wa JavaScript:
1function copyToClipboard(text) {
2 navigator.clipboard.writeText(text).then(() => {
3 alert('Kuratibu zimeandikwa kwenye clipboard!');
4 }, (err) => {
5 console.error('Haiwezekani kunakili maandiko: ', err);
6 });
7}
8
9// Matumizi
10const copyButton = document.getElementById('copyButton');
11copyButton.addEventListener('click', () => {
12 const coordinates = document.getElementById('coordinates').textContent;
13 copyToClipboard(coordinates);
14});
15Kazi hii inaweza kuitwa wakati Kitufe cha Nakala kinabonyezwa, ikipitia kuratibu zilizozalishwa kama maandiko yanayopaswa kunakiliwa.
