Need help with "int" and "char" function

Warning for wall of text!
You have been warned!

Since I'm a beginners beginner, im going to be posting the entire code here.
Been struggling with this simple code for like 5 hours. Been having ALOT of problems with just about everything but now finally the only problem left is that I can't seem to find a function for my "navigator" program to realise that the user is typing two variables (like 10 or 15) without using int.
As soon as I use char, c++ complains about it and says I can't use =>, <=.. ye nothing but strict "=".
Any function that allows me to use those signs and that can remember more than 1 input from the user? (Also reason i don't want to use "int" is because if the user types a letter, then the entire thing crashes :(

(This is a school project so the level of knowledge from my part is very limited. Also i'm new to this site so I hope it's a kind community :) )

Thanks in advance!

#include <iostream>
using namespace std;

	cout << "Ange distansen i km." << endl << endl;

	int dist;
	cin >> dist;

	if (dist >= 1) // <--- problem!
