Small knowledge point in C Language int * A [5] int (* B) [5]

Int main ()

{

Int * A [5];

INT (* B) [5];

Int I = 2, j = 3, K = 4;

B =;

A [0] = & I;

Printf ("% d/N", * a, * a [0], I );

Printf ("% d/N", a, a [0], & I );

Printf ("% d", B );

B ++;

Printf ("% d/N", B );

Getchar ();

}

 

[] The priority is higher than *, so a and B are two variables:

A Represents an array. Its array element storage type is int *;

The value of a represents the address value of the first element a [0] of the array. It is a pointer, that is, * A = A [0]. Note that the pointer type is const, that is, it cannot be changed.

 

B Represents an array pointer that points to an array of the int [5] type;

Because of the type of B, after B ++, it will offset sizeof (INT) * 5 bytes.
