why (++x) *(++x) results into 49 when x=5?

Answer 1

i will go fire up the pc!

Answer 2

As i understand it {} puts value in at the time of creation. = put value in after creation

so int x = 5; ( create a null int, put value 5 in x)
int x { 5 }; create int with value 5 (int is never null)

Answer 3

where ever you need create a new variable that needs an initial value you can use the {} method. using the = method is the same in most instances.

I have only encountered the {} method being required in creation of objects where the value is required at the time of the objects creation so far (classes). I will try and find some code in my library that shows this if you want

Answer 4

@4rontender: when using int x{5} you can change the value of x anytime. it is just another method of initializing a value

Answer 5

😂 why tho?

Answer 6

lol, we have totally ruined this guys question...

I can't find it in my code.. I initally saw it in the book Learning c++ for Game Programming

Here is some info: http://www.informit.com/articles/article.aspx?p=1852519

Answer 7

i can!

Answer 8

@svengat, cause I ran into an instance that required me to use {} instead of = the other day and I cannot remember the code off the top of my head 😄

Speaking of, I was watching some youtube last night.. everything is sooooo cheap there! 50 us cents for a 1 hour train trip wtf!! its like 6 usd here

Answer 17

makes me sigh they still teach void main() usage.

c will be 1 (or true) due to the statement
a!=10 ( a is not equal to 10)

but there is an error in what you wrote as c is undeclared.. missing a bool

Answer 18

@Anuj: See logical operators.

! means not. it will convert to boolean automatically if it is not already one

Answer 19

...I mean a complete new thread.

Answer 20
