Question

C++ program to read line comments.

This assignment will give you a little bit of practice with string parsing.

Your task is to write a program that reads in a .cpp file line-by-line, and prints out only the text that's after the // characters that indicate a single-line comment.

You do not have to worry about

/*
multiline comments
*/

though there will be a small amount of extra credit for programs that correctly extract these comments as well.

PLEASE GIVE IT A THUMBS UP, I SERIOUSLY NEED ONE, IF YOU NEED ANY MODIFICATION THEN LET ME KNOW, I WILL DO IT FOR YOU

#include <iostream>
#include <fstream>
#include <string>
using namespace std;
int main()
{
        fstream newfile;
        newfile.open("DynamicQueue.h", ios::in);
        if (newfile.is_open())
        {
                string tp;
                while (getline(newfile, tp))
                {
                        int i = 0;
                        for (i = 0; i < tp.size(); i++)
                        {
                                if ((i + 1) < tp.size())
                                        if (tp[i] == '/' && tp[i + 1] == '/')
                                                break;
                        }
                        i += 2;
                        int flag = 0;
                        while (i < tp.size())
                        {
                                cout << tp[i];
                                i += 1;
                                flag = 1;
                        }
                        if (flag == 1)
                                cout << endl;
                }
                newfile.close();
        }
}
