What is the formal difference between construction and initialization?

edit

Construction refers to the process of creating an object of a particular class, while initialization refers to the process of assigning initial values to the object's data members. Construction is the process of creating a new instance of a class, while initialization is the process of setting the initial state of that instance. Construction involves calling the constructor of the class, while initialization may involve using default values or values specified by the programmer. In general, construction is a broader term that includes initialization as one of its steps, but initialization is a more specific term that focuses on the assignment of initial values.
