Does incrementing the operator stores the value in the variable?

Question

like
a=9;
Console.WriteLine(a++);
will change the value of a to 10?

Answer 1

As a++ is same as a=a+1 so yes it will change it's value.
Position of "++" determines whether the value of 'a' must be used before or after the incrementing it

a++ means use and then change
++a means change and then use

Answer 2

I guess yes it does.

Answer 3

Yes, It does.

But in your case value will be printed first before it is increased.

Means, First value of ( a ) will be
printed
Then it will become 10

To print the value of ( a ) as 10 you should use:
Console.WriteLine(++a)
