Very simple sample of a pointer pointing to an array's base address.

pointers&arrays.c

#include <stdio.h>

void main(){
  int array[3] = {5, 10, 15};
  int* p;
  
  p = array;
  printf("p = %p, *p = %d\n", p, *p);
  
  p = &array;
  printf("p = %p, *p = %d\n", p, *p);
  
  p = &array[0];
  printf("p = %p, *p = %d\n", p, *p);
  
}
