    s = s + A[i];
  return s;
}
//-----------------------------------------------------------------------------
int Nelijo() {
  int s = 0;
  for (int i = 0; i < n; i++)
    if (A[i] == 0) s = s + 1;
  return s;
}

What I have tried:

codeblock shows error on 21 line: expected unqualified id before '{' token
34 line: setw was not declared
38 line: expected unqualified id before '{' token
It shows mistakes,but I dont know how to fix it

Line 34: You need to #include <iomanip>, which is where setw is defined.
Line 38: The } on line 37 closes the function Spausdinti. You then have a { at file scope. It looks like it's supposed to be the start of a function, but there's no function signature.
Line 21: Now that I can try to count up to that line number, void Skaityti(); is a function declaration only. Remove the ; if its definition is supposed to be the return 0 that follows.

Look at your code:

C++

fin.close();
}
//-------------------------------------------------------------------------------------------------------------
{                           <<<<<---- What's this doing here?
void Skaityti();

return 0;

Remove it, and see what happens
Also this:

C++

fout.close();
}
{                           <<<<<---- Eh?
Skaityti();
Spausdinti();
return 0;
}

And do yourself a favour: pick an indentation style as stick with it - you can even use the execrable 1TB if you must as long as you are consistent. Mix'n'match doesn;t make your code any easier to read - and makes problems like this harder to see.

Try to replace

C++

//-------------------------------------------------------------------------------------------------------------
{
void Skaityti();

  return 0;
}

with

C++

//-------------------------------------------------------------------------------------------------------------
void Skaityti();
{

  return 0;
}
