From what I’m able to understand:

  • declaration is when prototype or declaration is used to describe the features
  • definition is when a declaration is also assigned a literal or an object, such that a chunk of memory is allocated
  • initialization is the assignment of an object, either during definition or immediately after declaration
  • assignment is the setting of a value of a particular object at any stage of the program execution

Which of the follow terms overlap? Which of them is a superset/subset of each other?

    My understanding:

    int a = 1;
   // variable definition =
   // declaration + initialisation

int b; // variable declaration

b = 2  // variable initialisation,
       // type of assignment

a = 3  // variable assignment

int f(int x, int y);
   // function declaration

int g(int z) {
   return z;
}  // function definition

int f(int x, int y) {
   return x + y;
}  // function definition
