With boost::algorithm::split(), a given string can be split based on a delimiter. They can be applied in the same way as the functions for searching and removing, except they require an additional parameter – the replacement string (see Example 5.6). These include the following functions: boost::algorithm::replace_first_copy(), boost::algorithm::replace_nth_copy(), boost::algorithm::replace_last_copy(), boost::algorithm::replace_all_copy(), boost::algorithm::replace_head_copy() and boost::algorithm::replace_tail_copy().

Like the functions for searching strings or removing characters from strings, Boost.StringAlgorithms also provides functions for replacing substrings within a string. Std::cout << replace_tail_copy(s, 9, "LIBRARIES") << '\n' Therefore, the second call to boost::algorithm::to_upper_copy() correctly converts the string, which looks like this: BOOST C++ KÜTÜPHANELERI. Since this locale does have uppercase equivalents for umlauts, the entire string can be converted to uppercase. The Turkish locale is passed to the second call to boost::algorithm::to_upper_copy(). In the C locale, there is no uppercase mapping for characters with umlauts, so the output will look like this: BOOST C++ KüTüPHANELERI.

The first call to boost::algorithm::to_upper_copy() uses the global locale, which in this case is the C locale. Std::string upper_case2 = to_upper_copy(s, std::locale) Įxample 5.2 calls boost::algorithm::to_upper_copy() twice to convert the Turkish string “ Boost C++ kütüphaneleri” to uppercase. Std::string upper_case1 = to_upper_copy(s) Std::string s = "Boost C++ k\xfct\xfcphaneleri"
