What is the “-->” operator in C++? 21 answers

--> is not a new operator.

i --> 0

becomes effectively

i > 0; //Compare
i--; //and decrement

--> is not any operator. It is just the cocatenation of -- and > .

i-->0 it means compare the value of i and then decrement it.

So for better readability it can be written as

for (int i = 99; (i--)> 0;) {
