What is difference between initialization and assignment?..

Answer / jaroosh

Those answers are actually highly insufficient.
Here are some differences to point that come to my mind :
a) you CANT assign to a const variable, whereas you CAN
initialize it. For example :
const AXC d = 3; //OK! initialization
d = 3; //WRONG! cannot assign to const
b) initialization IS about creating object
assignment IS about setting some value to object
This is why in the following code :
AXC d = 3;
AXC x;
x = 2;
first line will require an appropriate constructor:
AXC(int i) { ... }
whereas the third line will use overloaded assignment "="
operator if its specified (if not, it will use constructor
like above):
AXC operator =(int x) { ... }
c) Initialization also calls copy constructors, while
assignment does not :
A c;
A d = c; //Calls copy constructor of A
A e;
e = c; //Calls assignment operator of A

What is difference between initialization and assignment?..

Answer / lucky

Some defference between Initialization and assignment
Initialization means whenever we initialize any var. at
declaration time.So as we initialize var. in init() in java
programming.For i.e.
prblic init()
{
int a=10;
}
Assignment means whenever we assigne any value in any var.
except const. variable.For i.e.
int a,b;
a=15; //right
b=a; //right
const c;
c=10 or c=a; //Worng
const d=20; //that is initialization

What is difference between initialization and assignment?..

Answer / sandeep mannarakkal

All object creation involves two steps,
1) Memory allocation
2) Memory initialization , so initialization is a part of object creation itself.
Assignment is the process of assigning values in to already available object.
Hope the concept is clear
