Expression of the C # tutorial [original]

The variables, data types, and type security are described earlier. We can see that the value assignment operator "=" is used ". In fact, C # also contains many operators for such processing.

By combining variables and literal values (which are called operands when operators are used) with operators, you can create an expression, which is the basic block for computing.

 

The range of operators is very extensive, simple, and complex. Some of them may only be used in mathematics.Program. Simple operations include all basic mathematical operations. For example, the + operator adds two operands together, while complex operations include processing them through the binary representation of the variable content. There are also logical operators used to process boolean values and value assignment operators, such as = operators.

 

Next we will first introduce the mathematical and value assignment operators, and the logical operators will be integrated in the Process Control Section, because the logical operators mainly discuss the Boolean logic of the control program flow.

 

Operators are roughly divided into the following three types:

 

● Unary operator, processing an operand

 

● Binary operator, processing two operands

 

● Ternary operator, processing three operands

 

Most operators are binary operators, with only a few unary operators and a ternary operator. The following describes mathematical operators, including unary operators and binary operators.
