The assignment operator evaluates the operating expression on the right side of the operator and uses the value to set the variable operating expression on the left side of the operator. Assignment operators mainly include simple assignment and compound assignment operators; the object types that can be placed on the left side of the assignment operator are variables, attributes, indexes, and events. If the types of operands on both sides of the assignment operator are inconsistent, you need to perform type conversion first, and then assign.
