Write a program to strip comments from an input “C” program file and store in output file. System Programming GTU 2150708

Program:-

#include<iostream>

#include<fstream>

using namespace std;

int main()

{

            fstream f1,f2;

            char ch;

            int c=0;

            f1.open("Sample.txt",ios::in);

            f2.open("Sample2.txt",ios::app);

            while(!f1.eof())

            {

                        f1.get(ch);

                        if(ch=='/')

                        {

                                    c++;

                        }

                        f2<<ch;

                        cout<<ch;

                        if(ch=='/' && c==2)

                        {

                                    while(ch!='\n')

                                    {

                                                f1.get(ch);

                                    }

                                    f2<<ch;

                                    cout<<ch;

                                    c=0;

                        }

            }

            f1.close();

            f2.close();

            return 0;

}
