Hi, I'm new to c++ and very confused about the prefix/postfix increment/decrement operators. IMO, they sometimes produce the same output and sometimes don't. It's confusing that if they can be interchangeable in certain situations.

Below two c++ code snippets are examples I came up with, and the first one has a postfix ++ and the second's is prefix.

It's definitely not the best example, and feel free to share yours if it has a better interpretation. Thanks for you help!

for (int i = 0; i < 5; i++) {

cout << "i - postfix++: " << i << endl;

}

for (int i = 0; i < 5; ++i) {

cout << "i - prefix++: " << i << endl;

}
