How Are C Arrays Represented In Memory?

Question

I believe I understand how normal variables and pointers are represented in memory if you are using C.

For example, it\'s easy to understand that a pointer Ptr will

A C array is just a block of memory that has sequential values of the same size. When you call malloc(), it is just granting you a block of memory. foo[5] is the same as *(foo + 5).

Example - foo.c:

#include 

int main(void)
{
    int foo[5];
    printf("&foo[0]: %tx\n", &foo[0]);
    printf("foo: %tx\n\n", foo);
    printf("&foo[3]: %tx\n", &foo[3]);
    printf("foo: %tx\n", foo + 3);
}

Output:

$ ./foo
&foo[0]: 5fbff5a4
foo: 5fbff5a4

&foo[3]: 5fbff5b0
foo: 5fbff5b0
