C++ post increment operator
WebSep 13, 2024 · Pre-increment operators will return the incremented value. Example: int a = 10; then ++a = 11, and the value of a =11. Whereas, Post-increment operators will return the incremented value and then increment the value. Example : int a = 10;, then ++a = 10, but value of a = 11; Now, ++a will be equivalent to : a = a + 1; return a; WebIf you use the ++ operator as a postfix like: var++, the original value of var is returned first; then var is incremented by 1. The -- operator works in a similar way to the ++ operator …
