Why this Error: a value of type “const int*” cannot be assigned to an entity of type “int*”?

问题

This is my code:

int i = 5;
const int * cpi = &i; //pointer to const
int * pi = cpi; //Error: a value of type "const int*" cannot be assigned to an entity of type "int*"

回答1:

i is mutable, cause it is not a const type. You try to store a int address in a const int address via cpi.

To solve it you have to actually hand over the values not the addresses.
