error: ‘nullptr’ was not declared in this scope i followed this tutorial :https://stackoverflow.com/questions/16509932/using-qt-creator-c-11-nullptr-is-keywordedbut there is still same error. Your g++/gcc version is too old. You need, at least V5.3.1 and even with V5.3.1, you cou...
It supports both C++11 and C++14. However, when I write a program using nullptr it is still telling me that 'nullptr' was not declared in this scope . What else do I have to do in order for nullptr to be accepted by the compiler? c++ c++11 nullptr tdm-gcc Share Follow edited M...

"nullptr is not declared" "first use in this function"2. One more question, I always write cin.get() to stay the console window so that I can see the result with enough time (otherwise it just disappears right after it appears.) ...
The following sample shows that when handles are declared and not explicitly initialized, they are default initialized to nullptr. // mcpp_nullptr_5.cpp // compile with: /clr using namespace System; ref class MyClass { public: void Test() { MyClass ^pMyClass; // gc type if (pMyClass...

Codeblocks编译C++出现to_string is not a member of std 或者 to_string was not declared in this scope的解决方法 包含的函数:to_string()! 然而在codeblocks等编译环境中,有时候会出现 to_stringwasnotdeclaredinthisscope等问题,原因是MINGW编译器不支持to_string()这个方法,这其实可以看成它的一个bug。
