- What are the differences between struct and class in C++?
The difference between struct and class keywords in C++ is that, when there is no specific specifier on particular composite data type then by default struct or union is the public keywords that merely considers data hiding but class is the private keyword that considers the hiding of program codes or data
- Proper way to initialize C++ structs - Stack Overflow
In C++ classes structs are identical (in terms of initialization) A non POD struct may as well have a constructor so it can initialize members If your struct is a POD then you can use an initializer struct C { int x; int y; }; C c = {0}; Zero initialize POD Alternatively you can use the default constructor
- Can a struct have a constructor in C++? - Stack Overflow
The reason for having struct in C++ is C++ is a superset of C and must have backward compatible with legacy C types For example if the language user tries to include some C header file legacy-c h in his C++ code it contains struct Test {int x,y}; Members of struct Test should be accessible as like C
- struct - C++ Structure Initialization - Stack Overflow
The designated aggregate initialization, where the initialization list contains that labels of each member of the structure (see documentation) available from C++20 onward Treating a struct like a C++ class - in C++ structures are actually special types of classes, where all members are public (unlike a standard C++ class where all members are
- c - typedef struct vs struct definitions - Stack Overflow
In C (not C++), you have to declare struct variables like: struct myStruct myVariable; In order to be able to use myStruct myVariable; instead, you can typedef the struct: typedef struct myStruct someStruct; someStruct myVariable; You can combine struct definition and typedefs it in a single statement which declares an anonymous struct and
- c++ - Memory alignment in C-structs - Stack Overflow
In your first struct, since every item is of size short, the whole struct can be aligned on short boundaries, so it doesn't need to add any padding at the end In the second struct, the int (presumably 32 bits) needs to be word aligned so it inserts padding between v3 and i to align i
- struct - Force C++ structure to pack tightly - Stack Overflow
Since C++11 † there's a standard way of specifying attributes and GCC supports the standard syntax as well: struct [[gnu::packed]] { short a; int b; } Clang pretty much copies GCC's syntax and hence both syntaxes above work on it too
- Overloading operators in typedef structs (c++) - Stack Overflow
Further, the typedef struct { } name; pattern is a C-ism, and doesn't have much place in C++ To answer your question about inline , there is no difference in this case When a method is defined within the struct class definition, it is implicitly declared inline
