  • c - Difference between - gt; and . in a struct? - Stack Overflow
    -> is a shorthand for (*x) field, where x is a pointer to a variable of type struct account, and field is a field in the struct, such as account_number If you have a pointer to a struct, then saying accountp->account_number; is much more concise than (*accountp) account_number;
  • When should I use a struct rather than a class in C#?
    struct Point { public int x, y; public Point(int x, int y) { this x = x; this y = y; } } Now, only one object is instantiated—the one for the array—and the Point instances are stored in-line in the array Struct constructors are invoked with the new operator, but that does not imply that memory is being allocated
  • c - typedef struct vs struct definitions - Stack Overflow
    A declaration begins with 'struct', a definition begins with 'typedef' Further, a struct has a forward declaration label, and a defined label Most people don't know this and use the forward declaration label as a define label Wrong: struct myStruct { int field_1;
  • Whats the difference between struct and class in . NET?
    CONSIDER a struct instead of a class: If instances of the type are small and commonly short-lived or are commonly embedded in other objects X AVOID a struct unless the type has all of the following characteristics: It logically represents a single value, similar to primitive types (int, double, etc ) It has an instance size under 16 bytes
  • Whats the syntactically proper way to declare a C struct?
    The second case wouldn't be possible here (unless you abandon sanity and use a void * instead) because the struct is anonymous, and the typedef doesn't happen until the struct is defined, giving you no way to make a (type-safe) pointer to the struct type itself The first version works fine for this use, but the third is generally preferred in
  • How to properly use `typedef` for structs in C? - Stack Overflow
    There's another variant: typedef struct tnode { int count; struct tnode *left; struct tnode *right; } TNODE; which uses the tagged structure name inside the structure because the typedef name isn't available until after the semicolon at the end For most practical purposes, this is equivalent to the first example
  • struct - C++ Structure Initialization - Stack Overflow
    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 private if not specified otherwise explicitly) as well as that when using inheritance they default to public: struct Address { int street_no;
  • Proper way to initialize C++ structs - Stack Overflow
    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 I compare 2 structures in C++? - Stack Overflow
    struct data { bool operator!=(const data p_rhs) const { return std::tie(x, y) != std::tie(p_rhs x, p_rhs y); } int x, y; }; Of course you should define all other operators, too Remember that you can implement most operators by delegating to others
