#include#include int main() { std::wstring strA = L"Hello"; std::wstring strB = L" world!"; strA.append(strB); std::wcout << strA << std::endl; return 0; }
#includeThis example demonstrates how to use the append function in a loop to concatenate a wstring multiple times. In this case, the loop iterates 3 times, resulting in the output of "Hello world! world! world!". Package Library: Standard C++ Library (stdlib) In both examples, the package library used is the Standard C++ Library (stdlib) as the wstring class is part of this library.#include int main() { std::wstring strA = L"Hello"; std::wstring strB = L" world!"; for (int i = 0; i < 3; i++) { strA.append(strB); } std::wcout << strA << std::endl; return 0; }
