#include#include int main() { std::string str = "C++"; str.append(" programming language"); std::cout << str << std::endl; return 0; }
#includeIn the above example, we used the Boost library to format the string using the format specifier and then used the str() function to convert the result to the string. In summary, String AppendWithFormat is a powerful method used in C++ programming to append formatted text to strings. It is available in various standard and third-party libraries and can help simplify and optimize code.#include int main() { std::string str = "C++"; std::string str2 = boost::str(boost::format("%1% programming language") % str); std::cout << str2 << std::endl; return 0; }
