You made a lot of mistakes. Here is the complete program:

#include <stdio.h>

#include <stdlib.h>

#include <string.h>

#define LICZBA_OCEN 5

struct Student
{ char imie_nazwisko[50];
  float oceny[LICZBA_OCEN];
};

float oceny[LICZBA_OCEN] = { 3, 3.5, 4.5, 5, 5 };

float wyswietl (Student * student)
{ printf ("%s\n", (*student).imie_nazwisko);
  int i;

  for (i = 0; i < LICZBA_OCEN; i++)
    {
     printf ("%.1f\n", (*student).oceny[i]);
    }
}

float srednia (Student * student)
{  float suma = 0;
   int i;
   for (i = 0; i < LICZBA_OCEN; ++i)
      {
        suma = suma + (*student).oceny[i];
      }
   return (float) LICZBA_OCEN;
}

Student s;

int main ()
{
    
strcpy (s.imie_nazwisko, "Novikov Oleksandr");
    
s.oceny[0] = 4.5;
s.oceny[1] = 5;
s.oceny[2] = 3.5;
s.oceny[3] = 3;
s.oceny[4] = 5;

wyswietl (&s);
printf ("Srednia: %.2f", srednia (&s));
}
