Std String Replace Substring Code Example

Example: c++ replace substrings

using namespace std;  string ReplaceAllSubstringOccurrences(string sAll, string sStringToRemove, string sStringToInsert) {    int iLength = sStringToRemove.length();    size_t index = 0;    while (true)    {       /* Locate the substring to replace. */       index = sAll.find(sStringToRemove, index);       if (index == std::string::npos)          break;        /* Make the replacement. */       sAll.replace(index, iLength, sStringToInsert);        /* Advance index forward so the next iteration doesn't pick it up as well. */       index += iLength;    }    return sAll; }   // EXAMPLE: in usage string sInitialString = "Replace this, and also this, don't forget this too"; string sFinalString = ReplaceAllSubstringOccurrences(sInitialString, "this", "{new word/phrase}"); cout << "[sInitialString->" << sInitialString << "]\n"; cout << "[sFinalString->" << sFinalString << "]\n";  /* OUTPUT: [sInitialString->Replace this, and also this, don't forget this too] [sFinalString->Replace {new word/phrase}, and also {new word/phrase}, don't forget {new word/phrase} too]  */
