6. Arithmetic operators and arithmetic expressions for C #

The C # programming language is very similar to other programming languages, and arithmetic and arithmetic expressions are the same.

1.

+ plus

-Minus

* Multiply

/ except

% Redundancy

These basic arithmetic operators can perform arithmetic operations on constants or variables.

In addition, there are self-increment operators and self-subtraction operators.

++

You can think of + + as the function name, followed by a pair of parentheses, this can be achieved self-increment.

+ + in the front, indicating the first self-increment, and then assign value. + + in the back, indicating the first assignment, and then self-increment.

Like what:

int A;

int b;

b=2;

a=++ (b); increment First, then assign value.

A= (b) + +; The value is first assigned and then self-increment.

-- can be used as a function name, followed by a pair of parentheses, which can effectively enhance readability.

-- before, it means to subtract first and then assign a value. -- after , the expression is first assigned and then reduced.

There are also complex arithmetic operators.

+ = For example:a+=3 is equivalent to a=a+3

-= For example:a-=3 is equivalent to a=a-3

*= such as:a*=3 is equivalent to a=a*3

/= such as:a/=3 is equivalent to A=A/3
