max_align_t - cppreference.com

typedef /*implementation-defined*/ max_align_t;

max_align_t is a type whose alignment requirement is at least as strict (as large) as that of every scalar type.

Pointers returned by allocation functions such as malloc are suitably aligned for any object, which means they are aligned at least as strictly as max_align_t.

#include <inttypes.h>
#include <stdalign.h>
#include <stddef.h>
#include <stdint.h>
#include <stdio.h>
#include <stdlib.h>
 
int main(void)
{
    size_t a = alignof(max_align_t);
    printf("Alignment of max_align_t is %zu (%#zx)\n", a, a);
 
    void *p = malloc(123);
    printf("The address obtained from malloc(123) is %#" PRIxPTR"\n",
            (uintptr_t)p);
    free(p);
}

Possible output:

Alignment of max_align_t is 16 (0x10)
The address obtained from malloc(123) is 0x1fa67010
