Answer 1

Answer:

#include <stack>

#include<iostream>

#include<fstream> // to read imformation from files

#include<string>

using namespace std;

int main() {

   stack<string> data;

   ifstream inFile("postfix.txt");

   string content;

   if (!inFile) {

       cout << "Unable to open file" << endl;

       exit(1); // terminate with error

   }

   while (getline(inFile, content)) {

       data.push(content);

   }

   inFile.close();

   return 0;

}

Explanation:

You were very close. Use the standard <stack> STL library, and make sure the stack elements are of the same type as what you're trying to add, i.e., std::string.
