What is different between i++ and ++i?

Question

For example:
Cout <<i++;
Cout << ++i;
What is different between 2 statement above?

Answer 1

++i first increment then use pre increment means in Expression first this will be solve means value will be increase by one

i++ means value then increment this is known as post increment
cout<<++i ; here initial value is 0 suppose so it will print 1

If u print this cout<<i++ it will print 0 then in next line it will increase

Answer 2

I++ is called post increment operator and ++I is called pre increment operator, both of the operator increase the value of I by 1, but post increment first perform the operation (like you're printing I) and then increment the value of I, and pre increment is opposite.
