Question

Write a C++ program that reads strings until "QUIT" input, which then displays all strings in the reverse order they were entered.

1. Tell the user the program will read strings until "QUIT" is entered.

2. Loop

1. Ask user for a string

2. If the string is "QUIT" break the loop, otherwise store data

3. Inform user data will be displayed in reverse.

4. Display ALL strings in reverse.

5. Free the space used to store the strings.

Answer 1

#include <iostream>

#include <cstring>

using namespace std;

// Drive code

int main()

{

  // variables declaration

  string str;

  string store[100];

  int i = 0;

  cout<<"Input\n";

  // infinite while loop that will break by user

  while (1){

    // getting string input from user

    getline(cin, str);

    // if user enters "QUIT" then

    if(str == "QUIT"){

      // break the loop

      break;

    }

    // otherwise

    else{

      // store the string in the array

      store[i] = str;

      // i incremented by 1

      i++;

    }

    

  }

  cout <<"\nOutput:\n";

  // output in reverse order

  for(int j=i- 1; j>=0; j--){

    cout << store[j] << endl;

  }

  return 0;

}

Answer 2

#include <iostream>

#include <cstring>

using namespace std;

int main()
{

  string str;

  string store[100];

  int i = 0;

  cout<<"Input\n";

  while (1){

    getline(cin, str);

    if(str == "QUIT"){

      break;

    }

    else{

      store[i] = str;

      i++;

    }

    

  }

  cout <<"\nString in reverse order:\n";
  for(int j=i- 1; j>=0; j--){

    cout << store[j] << endl;

  }
  return 0;
