Reverse the string elements

Here given code implementation process.

// C++ program
// Reverse the string elements

//Include header file
#include <iostream>

using namespace std;
class MyString
{
	public:
		//This function which is reverse the given text string
		//Time complexity O(n)
		string reverse_str(string text)
		{
			string result = "";
			//Traverse the string element from end to front order
			for (int i = text.size() - 1; i >= 0; i--)
			{
				//append new character to end of result
				result += text[i];
			}
			//When string are not empty then
			//Returns reversal form of given text
			return result;
		}
};
int main()
{
	MyString obj = MyString();
	string text = "ssoB ehT mA I";
	cout << "\n Before : ";
	cout << text;
	text = obj.reverse_str(text);
	cout << "\n After : ";
	cout << text;
	//Case 2
	text = "edoc siht ekil I";
	cout << "\n Before : ";
	cout << text;
	text = obj.reverse_str(text);
