for(int j=0;j<3;j++)

{

plik.close();

if (tab[0][0]=10)// i talk about this  , without this is allright , but i use this condition and i have problem .

{

liczba=tab[i][j];

if (tab[0][0] == 10)

= (single equal sign) is assignment; == (two equal signs) is  comparison.

Answer 2

Do you mean to do

if (tab[0][0] == 10)

?

condition :

if (tab[0][0]==10)

{

(...)

is correct .
