Confusion to understand!!

Question

pre increment and post increment 😣😣
pre decrement and post decrement😵😲

Answer 1

x = 1
if you do y = ++x ( x is 2 and y is 2 )
if you do y = x++ ( x is 2 and y is 1 )

it works the same with decrement

++x first increment it then assign it to y
x++ first assign it to y then increment it

Answer 2

indeed but its easy to learn
pre increment
x=10
y=++x //x=11 y=11
it will first increase and then y becomes x
with one element it will increase
x=10
x=++x //x=11
same with pre decrement

post increment
x=10
y=x++ //x=11 y=10
first y will become same as x, and after that x will increase
with one element x will stay the same
x=10
x=x++ //x=10
to increase use only
x=10
x++ //x=11
same with post decrement

Answer 3

The increment operator has two forms, prefix and postfix.

Prefix ++x increments the value, and then proceeds with the expression.
Postfix x++ evaluates the expression and then performs the incrementing

The decrement operator (--) works in much the same way as the increment operator, but instead of increasing the value, it decreases it by one.
