Question

Notes:
• The solution should be general to processing any file with the same schema, not only
applicable to the given file example.
• The program will be tested with data files with the same schema.

Assignment Marking Scheme

: • Program correctness (75%)

• Program indentation and readability (5%)

• Choice of significant names for identifiers (5%)

• Comments - description of variables and constants (5%)

COEN 244 (Winter 2017) Assignment 4: lo Deadline: Monday April 10 23:59pm, individual assignment Note: The assignment must be submitted on Moodle. Submission format: Create only ONE zip file (.gz, tar, .zip are acceptable. rar file is NOT acceptable) that contains all the header files, cpp files and test files. The name of the file must follow the template below: student id A4.zip; student id A4.tar or student id A4.gz. Submissions do not follow about format should be responsible for the consequences. Problem: Write a function that reads from a sequential file and writes to another sequential file. The file path and name are passed through arguments of the main function. int main int argc, char *argv0) For example, the file name is config dat, and the path is the current directory The schema of the file is shown below Field I Field II Field III int 12 1 1 81 6 3 4 3 9 70 Record I float 2 Record II 5.30 56.31 Record char (6 h a y K o z Record IV float 3 5.55 22.41 10.11

Explanation / Answer

//Please comment for any modification

#include <fstream>
#include <iostream>
#include <string>

using namespace std;

// Function to reverse a string
void reverseStr(string &str)
{
int n = str.length();
for (int i=0; i<n/2; i++)
swap(str[i], str[n-i-1]);
}
int main(int argc,char* argv[]){

   ifstream infile;
infile.open(argv[1]);
ofstream outfile;
outfile.open(argv[2],ios::out);
  
   string line;
   cout << "Displaying record from file " << endl;
   int num=1;
while (getline(infile, line))
   {
       cout << "RECORD " <<num<<" : "<< line << endl;
       reverseStr(line);
       outfile << line <<endl;
       cout << line << endl;
   }
   cout << "Now open reverse.txt file for displaying each record in reverse order " << endl;
infile.close();
outfile.close();
return 0;
}
