Ive done a little bit of programming in the past, mostly just dabbling.
After a long time of not touching an IDE, I am getting back into it. I just threw this quick project together to make sure I remember how to use classes and objects before I start playing with bigger projects.

I would love a quick critique to make sure there arent any glaring poor practices that could develop into bad habbits in the future.

I know the standard way to solve this problem is just time = distance/(velA+velB), but what would the point of using objects be if i didnt have the objects do something and change their status in someway?

what do you think, looks good?

/*

The goal for this practice program is to solve the common math word problem below using classes and objects.
I feel that using iterations rather than the basic math formula to solve, although clearly less efficient, would be more true to thinking in terms of objects.

Train A, traveling X miles per hour (mph), leaves Westford heading toward Eastford, 260 miles away.
At the same time Train B, traveling Y mph, leaves Eastford heading toward Westford.
When do the two trains meet? How far from each city do they meet?

#include "pch.h"
#include <iostream>
using namespace std;

class Train

public:
 Train(int, int);
 int getLocation();
 void update();
private:
 int location, velocity;
;

Train::Train(int loc, int vel) //to initialize the train object and set its location and velocity

 location = loc;
 velocity = vel;


int Train::getLocation() // returns the location of the train object

 return location;


void Train::update() // updates the train object for one iteration

 location += velocity;


int main()

 int velA, velB, distance; //to take the values from the user input
 int time; // to keep track of the number of iterations
 // time is declared here so it can be used outside of the for loop


 //input
 cout << "Enter velocity of the train from Westford:n";
 cin >> velA;
 cout << "nnEnter velocity of the train from Eastford:n";
 cin >> velB;
 cout << "nnEnter the distance between Westford and Eastford:n";
 cin >> distance;

 //initialize each train
 Train trainA(0, velA);
 Train trainB(distance, 0 - velB); //location of trainB is distance because the distance between an x coordinate at 0 and another x coordinate is equal to the second x coordinate
 //the velocity of trainB is the negative of velB because it is traveling in the opposite direction of trainA

 //run the sim
 for (time = 0; trainA.getLocation() < trainB.getLocation(); time++)
 
 trainA.update();
 trainB.update();
 

 //output
 cout << "nnThe Trains pass eachother after " << time << " hours."
 << "nAt that time, the Westford train is " << trainA.getLocation() << " miles from Westfordn"
 << "and the Eastford train is " << distance - trainB.getLocation() << " miles from Eastford.nn";
