C# variable initializations vs assignment
Just like in the title, could someone please explain what is the difference between Initialization and Assignment in C#? I'm preparing for a test and I wanted to know what's the best way to answer this type of question. Thanks
Cheers, n1te
回答1:
When you initialize a variable you're declaring it into existence.
PlasticCup mySippyCup = new PlasticCup();
When you assign, you're just saying "this water" goes into "this cup". The cup already exists.
mySippyCup = new PlasticCup();
回答2:
Initialization is assigning value while declaring the variable - int a = 1
Assignment is just assigning value to a variable - a = 1
By this definition, some say all initializations are assignments, but all assignments are not initializations.
