C++ do-while zanka se uporablja za večkratno ponovitev dela programa. Če število iteracij ni določeno in morate zanko izvesti vsaj enkrat, je priporočljivo uporabiti zanko do-while.
Zanka do-while C++ se izvede vsaj enkrat, ker se pogoj preveri po telesu zanke.
do{ //code to be executed }while(condition);

C++ Ugnezdena zanka do-while
Če v C++ uporabite zanko do-while znotraj druge zanke do-while, je to znano kot ugnezdena zanka do-while. Ugnezdena zanka do-while se v celoti izvede za vsako zunanjo zanko do-while.
