    Try noting down the address of a local variable. Call another function with a local
    variable declared in it and check the address of that local variable and compare!.

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

void stack(int *local1);

int main()
{
  int local1;
  stack(&local1);
  exit(0);
}

void stack(int *local1)
{
   int local2;
   printf("\nAddress of first  local : [%u]", local1);
   printf("\nAddress of second local : [%u]", &local2);
   if(local1 < &local2)
   {
     printf("\nStack is growing downwards.\n");
   }
   else
   {
     printf("\nStack is growing upwards.\n");
   }
   printf("\n\n");
}

    int main(){
  int a;
  int b;
  if(&a <&b)
    printf("growing up");
  else
    printf("growing down");
  getchar();
  return 0;
}

    ANS: growing down

    void  Up_down(int i)
{
   int ptr=&i;

   printf("%u  \n",ptr);
   up_down(j);
}

int main()
{
     Up_down(10);
     getchar();
     return 0;
}

    so By looking at the address of ptr u can say whether stack is growing up or down
