Pointer & reference And the reference pointer is used on a trial ------------------------ Int main () { Int val=1024; Int = &val *&ref } This can not be translated ------------------------ So I can be translated into the following two 1. ------------------------- Int main () { Int val=1024; Int = &val *pr Int = pr; *&ref } ------------------------- 2. ------------------------- Int main () { Int val=1024; Int = &val *const &ref } ------------------------- Thank you ask why is it so? Pointer & reference This is because int = & *&ref &val the site of the operation with officers to carry out their operation is the result of an interim target. In C + +, not for the temporary use of non-const object invoked, and this is a procedural error in the translation; Const objects for temporary use only, as you have done in the final procedure.
