Increment (+ +)The increment operator increments (adds one to) its operand and returns a value. If used Postfix, with operator after operand (for example, X + +), then it returns the value before incrementing. If used prefix with

First, arithmetic operationsThere are 34 types of operators in C, including the common subtraction operation 1. Addition Operation +L can also represent a plus: +5, +90 2, except that it can do addition operations. Subtraction Operation-In addition

An iterator is a data type that examines the elements inside a container and traverses the elements. You can override the subscript to access the elements of a vector object.Each container type defines its own iterator type, such as vector:
