Whats the difference between ++x, and x++... How do they work? And kindly give examples and challenges to test if i understand

Question

C++

Answer 1

let x = 1 the
x++ \\ first assign then increment.
after assign x = 2

x=1
++x = 2 \\ first increment then assign
x = 2

Answer 2

hi Nduta,

x=0
y=x++ like y=x and x=x+1 then y=0 and x=0+1=1
so
z=x++ like z=x and x=x+1 then z=1 and x=1+1=2

a=4
b=++a like a=a+x and b=a then a=4+1=5 and b=5

i hope that will be ok
bye

Answer 3

Hi @MBZH31 i dont understand the last part of it. Where a=4
Then b=++a

Answer 4

hi,
it's an other example with a and b instead of x and y
if you want, replace a by x and b by y.

in this part, we do an increment of a before
to initialyse b
