I wrote the code for the following problem but I keep on getting wrong answers its such a simple problem, but don’t know where am I going wrong in my code, here is my code for reference

#include<cstdio>
#include<iostream>
#include<cstring>
#include<string>

using namespace std;

int main(){


        string inputString;

        while( getline( cin , inputString ) ){


                int nDoubleQuotes = 0;

                for(int i = 0 ; i < (int)inputString.length() ; ++i){

                    if( inputString[ i ] == '"' ){
                        ++nDoubleQuotes;

                        nDoubleQuotes = nDoubleQuotes%2;

                        if( nDoubleQuotes == 1 )
                            cout << "``";
                        else
                            cout << "''";
                    }

                    else
                        cout << inputString[ i ];
                }

                cout << '\n';

        }

        return 0;
}

I think you should process and print each line one by one instead of printing character by character, I tried processing the whole string at once and then printing the entire paragraph but it showed WA, then I tried processing and printing 1 line at a time and it got AC, here’s a link to my ACed code, hope it helps :slight_smile: , http://ideone.com/ag2IJN

Could you explain why character by character reading gave WA? I had the same problem but I cant find a reason to it.
