Написала такой код:

#include<stdio.h> #include<stdlib.h> #include<string.h> #include<unistd.h>

void inspect_stack(void) { char stack_buf[16]; memset(stack_buf, ‘A’, sizeof(stack_buf));

char *heap_buf1 = malloc(24);
char *heap_buf2 = malloc(24);

strcpy(heap_buf1, "HELLO_HEAP_1");
strcpy(heap_buf2, "HELLO_HEAP_2");

printf("[*] PID процесса %d\n", getpid());
printf("[*] Адресс буфера в стеке: %p\n", (void*)stack_buf);
printf("[*] адресс heap_buf1: %p\n", (void*)heap_buf1);
printf("[*] Адрес head_buf2: %p\n", (void *)heap_buf2);
printf("нажмите ентер чтобы завершить....\n");
getchar();

free(heap_buf1);
heap_buf1 = NULL;
free(heap_buf2);
heap_buf2 = NULL;

}

int main(void) { inspect_stack(); return 0; }

Запустила так:

gcc -g -O0 touch_mem.c -o touch_mem

Вывелося полотно:
