Write a C++ program that extracts words inside the parentheses from the text, and stores the words into a vector.

Question

So below here I have the base of a program which reads text from a file, extracts the words inside the parantheses, and stores it into a vector. I've been stuck at this for a while now and would really appreciate any help with it. I can get the text from the file into the vector but I'm at a loss of extracting all the words inside the parantheses into another vector.

#include <iostream>

#include <fstream>

#include <string>

#include <vector>

using namespace std;

int main() {

ifstream fin("Lab8_2data.txt");

string text;

vector<string> word;

if(fin.fail()){

cout << "Unable to read the file.";

return -1;

}

getline(fin, text);

// you need to implement from here

fin.close();

return 0;

}

Answer 1

You can use the std::string::find() function to find where a parenthesis opens and where it ends. Then you just need to grab all the characters between the opening and closing parentheses via std::string::substr().

You can find examples with the above links (I deliberately did not disclose the whole solution in C++ for you, thus you can learn something while dealing with the problem).

Come back with your attempt to solve the problem if you get stuck!

Good luck!
