/*
 
A) const int;
B) int const;
C) const int *;
D) int * const;
E) int const * a const;
 
The answer is:
A) A is a constant integer.
B) A is a constant integer.
C) A is a pointer to the constant integer number (that is, the integer number cannot be modified, but the pointer can be)
D) A is a constant pointer to an integer (that is, the integer to which the Pointer Points can be modified, but the pointer cannot be modified ).
E) A is a constant pointer to a constant INTEGER (that is, the pointer to an integer cannot be modified, and the pointer cannot be modified ).

A) An integer)
B) a pointer to an integer (a pointer to an integer)
C) a pointer to a pointer pointing to an integer (a pointer to an intege) r
D) an array of 10 integers (an array of 10 integers)
E) an array with 10 pointers pointing to an integer. (An array of 10 pointers to integers)
F) A pointer to an array with 10 integers (a pointer to an array of 10 integers)
G) a pointer to a function. The function has an integer parameter and returns an integer number (a pointer to a function that takes an integer as an argument and returns an integer)
H) An array with 10 pointers pointing to a function, this function has an integer parameter and returns an integer (an array of ten pointers to functions that take an integer argument and return an integer)
 
The answer is:
A) int A; // an integer
B) int * A; // a pointer to an integer
C) int ** A; // a pointer to an integer
D) int A [10]; // an array of 10 Integers
E) int * A [10]; // an array of 10 pointers to Integers
F) int (* A) [10]; // a pointer to an array of 10 Integers
G) int (* A) (INT); // a pointer to a function a that takes an integer argument and returns an integer
H) int (* A [10]) (INT); // an array of 10 pointers to functions that take an integer argument and return an integer
