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.
