Detailed introduction: 1. Declare constants. The const keyword can be used to declare constants. The value of the constant cannot be modified during the running of the program. The constant can be a basic data type, such as integer, floating point number, character, etc., or a custom data type; 2. The const modifier in the function parameters.
