Question

I have been having a bit of trouble with my find and replace function I can get it to replace all characters but I only want it to change the characters that match the banned words.

Here is my code so far

class getTextData
{   
private:
    string currentWord;
    vector<string> bannedWords;
    vector<string> textWords;
    int bannedWordCount;
    int numWords;
    char ch;
    int index[3];
    ifstream inFile ();
public:
    void GetBannedList(string fileName);
    void GetWordAmount(string fileName);
    void GetDocumentWords(string fileName);
    void FindBannedWords();
    void ReplaceWords(string fileOutput);
};

for(int i = 0; i <= numWords; i++)
{
    for(int j = 0; j < bannedWordCount; j++)
    {
        if(string::npos != textWords[i].find(bannedWords[j]))
        {               
            textWords[i] = "***";
        }
    }
}

This just replaces with a fixed number of * but I want it to replace the characters it finds with a * not the whole word.

Thanks In Advance

Try this:

for(int i = 0; i <= numWords; i++)
{
    for(int j = 0; j < bannedWordCount; j++)
    {
        size_t pos = textWords[i].find(bannedWords[j]
        if(string::npos != pos))
        {               
            textWords[i].replace(pos, bannedWords[j].length(), 
                                 bannedWords[j].length(), '*');
        }
    }
}
