Initializing an expression in C #

Question

I have the following line of code

int i = (i = 20);

and it sets me to 20. Now my question is, are the two statements the same?

int a = 0;

int i = (a = 20);

and

int a = 0;

int i = a = 20;

Both operators will set the values ​​as i = 20and a = 20. Who cares?

If they are the same, then why are there bindings for equalizing the value?

Answer 1

From MSDN :

Assignment operators are right-associative, which means that operations are grouped from right to left. For example, an expression of the form a = b = c evaluates to a = (b = c).

Answer 2

Yes, these two are the same, but I would strongly discourage you from initializing variables like this. I would prefer:

int a = 0;
// Whatever the intervening code is

a = 20;
int i = a;
