What is a difference between ++x and x++?

Answer 1

a = x++ means assign the value of x to a, then increment x.
a = ++x means increment x, then assign the incremented value to a

Answer 2

Like,
x=2;
cout<<++x<<newl;
cout<<x;
\\print 3 and 3

Now:
x=2;
cout<<x++;
cout<<x;
//print 2 and 3

Answer 3

++x means at that moment the value +1 whereas x++ means when we use the value next time it is increased by 1

Answer 4

++x is prefix increment operation which follows the "change then use" rule which means that ++x will first increment the value of x by 1 and then use it whereas x++ is postfix increment operation which follows the "use then change rule" which means that the value of variable 'x' will be first used and then incremented

Answer 5

preincrement and posrimcrement

Answer 6

one is increment operator and the other one is decrement operator.

Answer 7

preincrement and postincrement
