</span>takto sa v C-cku stringy nespajaju. Vlastne, v C-cku neexistuju<br>
stringy, ale polia char-ov ukoncene nulami (a vlastne ani tie polia<br>
neexistuju, len kus pamate na ktory ukazuje smernik). Tie sa daju<br>
spajat trebars cez funckiu strcat, alebo mozno povedzme aj sprintf-om<br>
(ma vacsie moznosti, ale tazkopadnejsia metoda).<br>
