"Getting started with programming" about the redundancy problem in programming language

As a novice it rookie, has traversed countless detours and the wrong way, but now finally came.

Today is to talk about the problem of redundancy in programming languages, hoping to get some help from someone who has just entered the program.

As we all know, we have learned the rest of our primary school, but the programming language of the remainder is somewhat different, as follows:

1. Suppose int x=2, what is the value of expression (x + +)%3?

Answer: 2.
Calculate the residual after the first

2. The residual algorithm for negative numbers is as follows: for example

Beg 5%-3=? and -5%3=? The value.

5%-3= 5/-3=-1 2 is ( -3) X (-1) +2=5.

-5%3= -5/3=-1 2 i.e. (3) X (-1) -2=5.
