An array of elements of type char can be declared like this:

char v[6];  // array of 6 characters

Similarly, a pointer can be declared like this:

char* p; // pointer to character

In declarations, [] means ‘‘array of’’ and *means ‘‘pointer to.’’ All arrays have0as their lower bound, so v has six elements, v[0] to v[5] . The size of an array must be a constant expression. A pointer variable can hold the address of an object of the appropriate type:

char∗ p = &v[3]; // p указывает на четвёртый элемент массива v
char x = ∗p; // *p является объектом, на который указывает p

In an expression, prefix unary ∗ means ‘‘contents of’’ and prefix unary & means ‘‘address of.’’ We can represent the result of that initialized definition graphically:
