Question

C++: only use Strings in this question.

Write a program to read the input file, shown below and write out the output file shown below. Use only string objects and string functions to process the data. Do not use c-string functions or stringstream (or istringstream or ostringstream) class objects for your solution. The idea of the program is to read the text file into 4 variables and rearrange the output. please explain as you go through.

here is the start code i wrote (change if needed that okey):

#include <iostream>
#include <fstream>
#include <string>
using namespace std;

main()
{
string team,team2;
string score,score2;
ifstream myfile("input.txt");
/*if (myfile.is_open())
{
while ( getline )
{
cout << city << score<< ' ';
}
myfile.close();
}

else cout << "Unable to open file";
*/
return 0;

}

Explanation / Answer

The complete working code in c++ for the above problem :

#include <iostream>
#include <fstream>
#include <string>
#include <vector>
#include <algorithm>

using namespace std;

unsigned int split(const std::string &txt, std::vector<std::string> &strs, char ch)
{
   unsigned int pos = txt.find(ch);
   unsigned int initialPos = 0;
   strs.clear();

   // Decompose statement
   while (pos != std::string::npos) {
       strs.push_back(txt.substr(initialPos, pos - initialPos + 1));
       initialPos = pos + 1;

       pos = txt.find(ch, initialPos);
   }

   // Add the last one
   strs.push_back(txt.substr(initialPos, std::min(pos, txt.size()) - initialPos + 1));

   return strs.size();
}

int main()
{
   string team, team2;
   string score, score2;
   string line;
   ifstream myfile("input.txt");
   ofstream outputFile("output.txt");

   vector<string> words;

   if (myfile.is_open())
   {
      while (getline(myfile, line) )
   {
          words.clear();
          split(line, words, ' ');
          if (words.size() == 4)
          {
              words[1].erase(2,1);
              outputFile << words[0] << "over " << words[2] << " " << words[1] << "to " << words[3] << endl;
          }
   }
   myfile.close();
   }
   else cout << "Unable to open file";
   outputFile.close();
   return 0;

}
