Hey everyone, I need help in template constructor specialization, checked the internet for hint but none work as expected. I have a class Value and need 3 constructor to be with Value(AnyIntegerType), Value(AnyFloatingType), and Value(AnyOtherType) for Integer template <typename T, std::enable_if<std::is_integral<T>::value>* = nullptr> Value(T val) for FloatingPoint template <typename T, std::enable_if<std::is_floating_point<T>::value>* = nullptr> template <typename T, std::enable_if<!std::is_floating_point<T>::value && !std::is_floating_point<T>::value>* = nullptr> Value(T val) Value(T val)

C and C++ allow pointers to incomplete types. So your SFINAE does not work as expected. Usually std::enable_if is used to disable certain template instantiations because it leads to generation of an incomplete type. But here you declare a pointer to such an incomplete type and also initialize it with nullptr. So the compiler will allow all instantiations in this case which leads to ambiguity.

hi im new to C++ const char * foo = "example"; const char* foo2 = foo is there a way to convert or cast const char* foo2 variable to utf8 without changing to prefix u8"example"

I can use this only for scalar type? X some_shit(vector<X>& x_){ vector<X> x; x.reserve(x_.size()); }

You will have to use facets and codecvt. It is not very straightforward to use but once you get the hang of it, you can use them fairly easily for all your localisation and internationalisation needs.

So something is bothering me. Can you put a C file in an image. I'm doing it for educational purposes so I'm not gonna make a malware because I'm a beginner in programming and I am learning C but how do i put a C file in an image like merge? On android💀is there any third party app for it?

Heya guys, can anyone tell me if I can take input from user without pressing the enter key? Like just a character (just like getch() used to do). I want to do this on linux.

Got it, it can be done with ncurses👍

Yes you can hide data in an image; tools like https://steghide.sourceforge.net/ exist.

It's available it's a tool call steghide it is a command line tools you can try googling the name

Write a program in C++ to implement stack operations. Write a program in C++ to implement queue using array.

Write a program in C++ to implement stack operations. Write a program in C++ to implement queue using array.

Behaviors of example "if the default constructor is not written in the program code, the compiler will automatically add some functions"

cpp books have those informations for example expert c++

Anyone on? I want help with a code in c

hi does anyone here know how i can turn negative numbers into positive with out using any lib

×(-1)

?

?

is that your homework by any chance?

@K11M1 😂😂😂

Is there any books, blog or document demonstrate about the compiler behavior when compiling C++ ?

Advanced C & C++ compiling, for example

is that your homework by any chance?

Practice file program that i don't understand what's the logic i use for program

hi does anyone here know how i can turn negative numbers into positive with out using any lib

What the hell, man…

hi does anyone here know how i can turn negative numbers into positive with out using any lib

~ your_number + 1

u to smart for me -42 +1 = positive number hahahaha

the vm was not a question

?

i just had to number * -1 if its less then 0

yeah but using ~n + 1 is faster

why what does ~ mean

nvm never mind

what preprocessor and preprocessor directive?

Can someone explain this?

like... what it is ? or what it does? or what do you mean by "what"?

What's it and what does it do
