C++ Append To Std::string Code Example

Example 1: append string c++

// appending to string #include <iostream> #include <string>  int main () {   std::string str;   std::string str2="Writing ";   std::string str3="print 10 and then 5 more";    // used in the same order as described above:   str.append(str2);                       // "Writing "   str.append(str3,6,3);                   // "10 "   str.append("dots are cool",5);          // "dots "   str.append("here: ");                   // "here: "   str.append(10u,'.');                    // ".........."   str.append(str3.begin()+8,str3.end());  // " and then 5 more"   str.append<int>(5,0x2E);                // "....."    std::cout << str << '\n';   return 0; }

Example 2: c++ append a char to a string

// string::operator+= #include <iostream> #include <string>  int main () {   std::string name ("John");   std::string family ("Smith");   name += " K. ";         // c-string   name += family;         // string   name += '\n';           // character    std::cout << name;   return 0; }
