Zanka for C++ se uporablja za večkratno ponovitev dela programa. Če je število ponovitev določeno, je priporočljivo uporabiti zanko for kot zank while ali do-while.

Zanka C++ for je enaka C/C#. Lahko inicializiramo spremenljivko, preverimo pogoj in povečamo/zmanjšamo vrednost.

 for(initialization; condition; incr/decr){ //code to be executed }

C++ ugnezdena zanka For

V C++ lahko uporabimo zanko for znotraj druge zanke for, znana je kot ugnezdena zanka for. Notranja zanka se v celoti izvede, ko se zunanja zanka izvede enkrat. Torej, če se zunanja zanka in notranja zanka izvedeta 4-krat, bo notranja zanka izvedena 4-krat za vsako zunanjo zanko, tj. skupno 16-krat.

C++ Infinite For Loop

Če v zanki for uporabimo dvojno podpičje, bo izvedena neskončnokrat. Oglejmo si preprost primer neskončne zanke for v C++.
