boost/algorithm/string/replace.hpp

Exmaple

    // 破壊的な変更を行うバージョン
    {
        std::string s = "Hello Jane, Hello World!";

        // 全ての"Hello"を"Goodbye"に置き換える
        boost::algorithm::replace_all(s, "Hello", "Goodbye");
        boost::algorithm::replace_all(s, "Goodbye", "Goodbye1");
        std::cout << s << std::endl;
    }

    // コピーを返すバージョン
    {
        const std::string s = "Hello Jane, Hello World!";

        const std::string result = boost::algorithm::replace_all_copy(s, "Hello", "Goodbye");
        std::cout << result << std::endl;
    }

    // 先頭、最後
    {
        string str1 = "Hello  Dolly, Hello World! Hello World!";
        boost::algorithm::replace_all(str1, "Hello", "Bye");
        std::cout << str1 << std::endl;
        boost::algorithm::replace_first(str1, "Bye", "Bye1");
        std::cout << str1 << std::endl;
        boost::algorithm::replace_last(str1, "Bye", "Bye1");
        std::cout << str1 << std::endl;
    }
