Well for the inline..
Advantages-
inline is a compiler directive so it will make compiler to copy the whole function where it is required , So there is no stack frame required in the stack section for storing the address of the function .
Disadvantages-
inline should only be used for the long functions as it will require more space as well as more calculation time.
For the const...
Advantages--
If you want any variable to keep constant through out the program then you can use const keyword. It is stored in the read only of the initalized data segment , even the pointer storing it's location cannot change the value of it, pointer can just change the address to point at some other location.
Disadvantages--
As the const is not flexible so mostly people use #define which is more flexible than const
