After compiling this what you see on the picture, it asks me the first question 'Ubaci ime pikovog soka' and when I type sth. it stops working, I think I did everything as Bucky did.What's wrong here? Btw Insert picture button isn't working also :D here is the code:

int main()
{
    struct sokovi{
    int sifraSoka;
    char nazivSoka;
    char nazivDobavljaca;
    int zapremina;
    };

    struct sokovi pik;
    struct sokovi gazirani;

    pik.sifraSoka = 17;
    gazirani.zapremina = 567;

    puts("Ubaci ime pikovog soka");
    gets(pik.nazivSoka);

    puts("Stavi ime dobavljaca gaziranok soka");
    gets(gazirani.nazivDobavljaca);

    ...
