You aren’t going to be able to avoid some calculation. int k = n % 10; will get you the last decimal digit, as that assignment gives k the remainder of division by 10. 3 solved How to get a right shifted number without actual calculation?
Remove #include “ar.cpp” from main. You’re defining insert two times. There is no difference between the relevant rules in C++11 and C++14. You did something different between your test runs that has nothing to do with the language version. I also recommend not calling it .cpp. Conventionally, nothing you include should be called .cpp. Since … Read more
You are missing some typenames and have the class template Move definition repeated three times. Th below code works: #include <iostream> #include <type_traits> using namespace std; template <typename T> class remove_all_pointers{ public: typedef T type; }; template <typename T> class remove_all_pointers<T*>{ public: typedef typename remove_all_pointers<T>::type type; }; template <typename T> class remove_all_pointers<T* const>{ public: typedef … Read more
Introduction Compile time restricted templates are a powerful tool for creating efficient and reusable code. They allow developers to create templates that can be used in multiple contexts, while still ensuring that the code is optimized for the specific context in which it is used. This article will discuss how to create compile time restricted … Read more
You can use some user defined functions to calculate the conversion from Celsius to the other units. Then you only need one loop: #include <iostream> #include <iomanip> using std::cout; using std::cin; using std::setw; // define some constant const double zero_point = 273.15; constexpr double factor = 9.0 / 5.0; const double max_cels = 5000; // … Read more
This code works correctly on clang and g++ (using C++11): http://coliru.stacked-crooked.com/a/c8071ab447e10a31 Produces a std::tuple with Max_N elements of the same type, and fills it up with the first values of the given list. If less elements in list than Max_N, fills the last elements with sentinel values. In practice, using std::array<C, N> may be more … Read more
load of misaligned address 0x6280033f410a for type ‘uint32_t’ … How do I need to fix this? You need to create an aligned object (such as a variable), and copy the content from the misaligned address: std::uint32_t u32; std::memcpy(&u32, data, sizeof u32); This assumes that you intend to read sizeof u32 bytes from that address and … Read more
Multpile definition of a header declared variable This is already a violation of the One Definition Rule. The simple answer is “don’t”. You can only declare in a header, via extern, and define in a single .cpp file. 2 solved Multpile definition error of a header declared variable when there’s just one definition/declaration [duplicate]
You’re the one running gcc (or g++). It’s a compiler, used by developers. End-user systems may not have any version of gcc. It’s glibc and libstdc++ you need to worry about. But in general, Linux does not aim for binary compatibility. Do not expect any binary executable to run properly on any other distribution/major version. … Read more
The only reason a function should accept a std::shared_ptr as a argument is if it may need to share or modify the ownership of the resource. If not, don’t pass a std::shared_ptr. If the function will definitely need to take shared ownership then it should accept a std::shared_ptr by value. Only accept a std::shared_ptr& if … Read more
The honour for the solution goes to @molbdnilo , who noticed a case of undefined behaviour (delete neueTankstelle led to dangling pointer in list). @hyde mentioned the possible case of different file endings. solved Why is my street printed on Linux, but not on Windows?
std is a namespace.std::vector is a class template in the std namespace, which makes std::vector<double> a class.std::vector<T>::iterator is a nested type under std::vector<T>. If you want to define an object of type std::vector<double>, you use: std::vector<double> obj; If you want to define an object of type std::vector<double>::iterator, you use: std::vector<double>::iterator iter; 2 solved why do … Read more
Looks like you have a semi-colon where a left curly brace should be to open the function scope solved std::stringstream object unrecognized in std::to_string replacement function [closed]
You have p as some pointer. Who is going to allocate the memory that pointer points to? In C it is almost always the responsibility of the caller to allocate any buffers before the call. If you don’t want to, then use a std::string instead. solved file handling I/O c++ error
That is undefined behavior. There is no guarantee, if these zeros are there, that just accidentally is true. The explanation is, that for some random reason at these places in memory a 0 was stored before it was reused for your purpose here. Since you allocate your arrays on the stack, these zeroes are probably … Read more
