Keyword order when arrays and const variables are declared in C ++

1.When defining an array, you can only use the following sequence: Typename arrayname [size]; // correctThe following sequence cannot be used: Typename [size] arrayname; // ErrorThis is different from the array defined in Java. 2.When defining a const object, you can use the following sequence: Const typename varname = initializationvalue; // correctYou can also use the following sequence: Typename const varname = initializationvalue; // correct//////////////////////////////////////// //////////////////////////////////////// /// Usage of const, <valid tive C ++ Chinese version. p18 in the Third Edition: Although the const syntax is changeable, It is not unpredictable. if the keyword const appears on the left of the asterisk, it indicates that the indicated object is a constant; if it appears on the right of the asterisk, it indicates that the pointer itself is a constant; if it appears on both sides of the asterisk, it indicates that both the indicated object and pointer are constants.Therefore: Const typename * PTR;And Typename const * PTR;All indicate that PTR points to a constant: Typename * const ptrc = & constant;There is no equivalent syntax. the pointer ptrc itself is a constant and must be initialized.
