MHB Find First Free Position in Array in $O(\log n)$ Time Complexity

[I like Serena]

Should I declare [m]starsystem[/m] outside the if?? (Wondering)

The would help yes.
The life time of an object ends when we get to the matching closing brace. (Nerd)

What do you mean?? (Wondering)

What do you mean?? (Wondering)

When you have:

void function()
{
  int a = 2;
  {
    int a = 3;
    printf("%d\n", a);
  }
  printf("%d\n", a);
}

what do you think gets printed? (Wondering)

It will print:

3
2

right?? (Wondering)

3
2

right?? (Wondering)

Yep. (Nod)

When "int a = 3" is declared, local stack memory is allocated for it.
Furthermore it "hides" the "a" that was declared earlier.
When the closing brace comes by, the local stack memory is automatically released.
Afterwards, the original "a" becomes visible again. (Nerd)

Ahaa... Ok! (Muscle)I have also an other question...

When I declare 'starsystem', before the if statement, do I write it as followed??

[m] starsy_t *starsystem;[/m]

Or should I set it equal to [m]NULL[/m] ??

It is good practice to always set a pointer to NULL if you're not setting it to any other specific value. (Smirk)
