Question

Need help in C++

• "N" instructs the drone to move north 1 space - for example, from (0,0) to (0,1). • "S" instructs the drone to move south 1 space. • "E" instructs the drone to move east 1 space. • "W" instructs the drone to move west 1 space. The commands in the string are separated for spaces. An example command string would be 'NNWN" Write a function that takes a string argument containing commands for the drone. Simulate the motion of the drone starting at the origin (0,0) and following each of the commands in succession. Your function must print the drone's location after each command on a new line to STDOUT. Be sure to include the starting point! After the drone completes all commands, print the drone's final Euclidean distance (as the crow flies) from the origin, cruncated to 2 decimal places. A sample function call: (fly "NNWN") Corresponding output: (0,0) (0,1) (0,2) (-1,2) (-1,3) euclidean distance: 3.16

#include <bits/stdc++.h>

using namespace std;

// Complete the fly function below.

void fly(string commands) {

}

int main()

{

string commands;

getline(cin, commands);

fly(commands);

return 0;

}

#include <bits/stdc++.h>
#include <iostream>
#include <iomanip>
#include <cmath>
#include <string>
using namespace std;

// Complete the fly function below.
void fly(string commands) {
    char direction;
    int x = 0, y = 0;
    cout << "(" << x << "," << y << ")" << endl;
    for (int i = 0; i < commands.size(); i += 2) {
        direction = commands[i];
        if (direction == 'N') {
            y++;
        } else if (direction == 'S') {
            y--;
        } else if (direction == 'E') {
            x++;
        } else {
            x--;
        }
        cout << "(" << x << "," << y << ")" << endl;
    }
    double distance = sqrt(x*x + y*y);
    cout << "euclidean distance: " << setprecision(2) << fixed << distance << endl;
}

int main() {
    string commands;
    getline(cin, commands);
    fly(commands);
    return 0;
