  • What is the difference between initialization and assignment?
    Yet, at the C++ technical level initialization has already been done, by a call of std::string's default constructor, so at this level one thinks of the declaration as initialization, and the assignment as just a later change of value So, especially the term "initialization" depends on the context!
  • c++ - What does initialization exactly mean? - Stack Overflow
    In practice, constant initialization is usually performed at compile time, and pre-calculated object representations are stored as part of the program image If the compiler doesn't do that, it still has to guarantee that this initialization happens before any dynamic initialization
  • What distinguishes the declaration, the definition and the . . .
    Initialization includes things like the zero initialization of variables with static lifetime, and default constructors, as well as what you show (And to add to the confusion: in C, initialization can be the first time the variable is assigned to; e g in statements like "taking the value of an uninitialized variable"
  • Java: define terms initialization, declaration and assignment
    Initialization: Initialization is when we put a value in a variable, this happens while we declare a variable Example: int x = 7;, String myName = "Emi";, Boolean myCondition = false; Assignment: Assignment is when we already declared or initialized a variable, and we are changing the value You can change value of the variable as many time
  • Initialization vs Assignment in C - Stack Overflow
    Using "initialization" to refer to both cases is confusing because there is a very important distinction What you refer to as the "first way" is usually called "static initialization" When you write "static int x[2]={1,2}", the compiler will generate a data block containing the values "1, 2" and then initialize X to point to the memory
  • What exactly does static initialization mean? - Stack Overflow
    Static initialization applies to variables with static or thread storage duration It happens in two phases First, variables with static storage duration are zero-initialized before any other initialization Then constant initialization is performed Constant initialization has to be one of the following three possibilities (§3 6 2 2):
  • What is an lt;init gt; method in Java? Can it be overridden?
    Have a look at the Java Virtual Machine Specification, chapter 2 9 It say on the <init> name: At the level of the Java Virtual Machine, every constructor written in the Java programming language (JLS §8 8) appears as an instance initialization method that has the special name <init>
  • c++ - Vector of structs initialization - Stack Overflow
    I want know how I can add values to my vector of structs using the push_back method struct subject { string name; int marks; int credits; }; vector lt;subject gt; sub; So now how can I add
  • C++ - initializing variables in header vs with constructor
    Even though it's supported, this type of initialization will create bugs that will be pretty hard to track down It's the type of "aesthetic optimization" that you will regret a couple months down the road See the example below: class_x_1 h: class X { private: int x = 10; public: int GetX(); }; class_x_2 h:
