String Replace:
bool str_replace(std::string& str, const std::string& from, const std::string& to) { size_t start_pos = str.find(from); if (start_pos == std::string::npos) return false; str.replace(start_pos, from.length(), to); return true; } //usage: std::string str = "John XXX"; str_replace(str, "XXX", "Doe");
String Tokenize:
std::string input = "We, are, all, strangers, here"; // our input char delim = ','; // our delimiter std::istringstream ss(input); std::string token; std::vector tokens; while(std::getline(ss, token, delim)) { tokens.push_back(token); } // tokens contain the array of tokenized strings separated by delimiter
