Code:

#include<iostream>
#include<fstream>
#include<string>
#include<algorithm>
#include<vector>
using namespace std;

string path = "C:\\Users\\Reality\\Desktop\\random\\test.txt";
vector<double>vec;
int main() {
	fstream fin;
	string s;
	fin.open(path, ios::in);
	while (getline(fin,s,',')) {
		double d = stod(s);
		vec.push_back(d);
	}
	sort(vec.begin(), vec.end());
	for (int i = 0; i < vec.size(); i++) {
		cout << vec[i] << endl;
	}
