C++ Programming Help Replacing Four Letter Words With "Love"?

I am trying to write a program that reads in a line of text and replaces all four letter words with the word "Love".


Example:


I hate you! TO I love you!





This is what I got so far.





# include %26lt;iostream%26gt;


# include %26lt;string%26gt;


using namespace std;





int main(){





string sentence;


cout%26lt;%26lt;"Please enter a sentence."%26lt;%26lt;endl;


getline(cin,sentence);


int spaceOne=0, spaceTwo=0;





while(spaceOne%26lt;sentence.size())


{


spaceOne = sentence.find(' ', spaceOne);





spaceTwo = sentence.find(' ', spaceOne);





if((spaceTwo-spaceOne)==4)


{


sentence.replace(spaceOne+1, 4, "love");


spaceOne = spaceTwo;





} else


{


spaceOne=spaceTwo;


}


}


cout%26lt;%26lt;sentence;


return 0;


}

e.g.


// s1, s2 are char arrays


s1 = "I really hate you";


replace_all(s2, s1, "hate", "love");
Reply:You need to find a way to make sure that spaceOne is not always equal to spaceTwo like it is in your implementation.





I believe this is all you need, but I didn't test it:


spaceTwo = sentence.find(' ', spaceOne+1);
