The operator is the symbol used for the operation, acting on one or more operands. (operand: The data that participates in the operation. ）

operator + + and--

+ +, called the self-add operator . For example, number 22nd today, a day next year, written in code is this:

int number=22;//today No. 22nd

number=number+1;//tomorrow, in today's days on +1;

number++; Number=number+1; The function is the same, the value of the variable is +1.

--called the self-decrement operator . Today, for example, number 22nd, yesterday, a day less, written in code is this:

int number=22;//today number 22nd number--;//equals to number=number-1;

Other than that

number++; with number--; can also write + +

number; or--number;

Variable name + +

+ + variable Name
