#include <iostream>

#include <string>

using namespace std;

class Reverse {

private:

string text; //text에 빈 문자열 준다.

int size;

public:

Reverse();

void reverse_str();

~Reverse() { cout << "Excellent!!" << endl; }

};

Reverse::Reverse() {

string text;

cout << "입력한 문자를 거꾸로 출력하는 프로그램" << endl;

cout << "문자열 입력(exit 입력시 종료) >> " << endl;

getline(cin, text);

}

void Reverse::reverse_str() {

for (;;) {

if (text == "exit")

break;

for (int i = text.length() - 1; i >= 0; --i)

cout << text[i];

cout << endl;

cout << "입력한 문자열의 역순 출력 >>" << endl << text << endl;

}

}

int main()

{

Reverse();

void reverse_str();

}

Take an English sentence and print it backwards

you define string text again in  Reverse function so value store in it which you can not access because they are global variable .just remove it and call function obj of class.no need of exit if you want you print a message in if condition

#include <iostream>

#include <string>

using namespace std;

class Reverse {

private:

string text; //text에 빈 문자열 준다.

int size;

public:

Reverse();

void reverse_str();

~Reverse() { cout << "Excellent!!" << endl; }

};

Reverse::Reverse() {

string text;

cout << "입력한 문자를 거꾸로 출력하는 프로그램" << endl;

cout << "문자열 입력(exit 입력시 종료) >> " << endl;

getline(cin, text);

}

void Reverse::reverse_str() {

if (text == "exit")
cout<<"wrong ";

for (int i = text.length() - 1; i >= 0; --i)

cout << text[i];

cout << endl;

cout << "입력한 문자열의 역순 출력 >>" << endl << text << endl;

}
int main()

{
Reverse obj;
Reverse();

obj.reverse_str();

}
