C++ do-while petlja koristi se za ponavljanje dijela programa nekoliko puta. Ako broj ponavljanja nije fiksan i morate izvršiti petlju barem jednom, preporučuje se korištenje do-while petlje.

C++ do-while petlja se izvodi barem jednom jer se uvjet provjerava nakon tijela petlje.

 do{ //code to be executed }while(condition);

C++ ugniježđena do-while petlja

U C++-u, ako koristite do-while petlju unutar druge do-while petlje, to je poznato kao ugniježđena do-while petlja. Ugniježđena do-while petlja se u potpunosti izvršava za svaku vanjsku do-while petlju.
