--x has "-- " preceding x which means whenever code runs and it is going to work on x then it will first decrease x by1 and then use it .
but in case of x-- the code will first use the current value of x once and then decrease it with on
it would not decrease x till its current value is used once 😉hope u got it .......

Yep, you got it!
int x = 3;
cout << --x; // outputs 2
int y = 3;
cout << y--; // outputs 3, then decrements y
cout << y; // so this outputs 2 now.

--x decrements the value first and uses the new value in the statement.
x-- first executes the statement and decrements the value of x after that.
