I. Assignment operators

　　The data type of an expression is compatible with the type of the left variable

1>: General Assignment

2>: Conforming to assignment, reflexive assignment

Two. Conditional operators

The conditional operator is also called the ternary operator. Syntax format: "(condition)?" Expression 1: Expression 2 ", if the condition is true, the value of the entire expression is the value of expression 1, and if the condition is not true, the value of the entire expression is the value of expression 2.
