Bagaimanakah program C++ yang ditulis dalam vs2017 boleh disalin ke Qt Creator tanpa melaporkan ralat?
Ini adalah sekeping kod yang saya temui dalam talian Tidak ada masalah untuk meletakkannya dalam vs2017. Kebanyakan fail pengepala tidak boleh digunakan dalam Qt, dan beberapa kata kunci tidak boleh digunakan dalam Qt Ralat dan amaran akan diprogramkan di bawah tetingkap.
