C++ do-while loop används för att iterera en del av programmet flera gånger. Om antalet iterationer inte är fixerat och du måste köra loopen minst en gång, rekommenderas att du använder do-while loop.

C++ do-while loop exekveras minst en gång eftersom villkoret kontrolleras efter loop body.

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

Låt oss se ett enkelt exempel på C++ do-while loop för att skriva ut tabellen med 1.

C++ Nested do-while loop

I C++, om du använder do-while loop inuti en annan do-while loop, kallas det kapslad do-while loop. Den kapslade gör-under-slingan exekveras fullt ut för varje yttre gör-under-slinga.

Låt oss se ett enkelt exempel på kapslad do-while loop i C++.

 #include using namespace std; int main() { int i = 1; do{ int j = 1; do{ cout&lt; <i<<\'
\'; j++; } while (j <="3)" ; i++; (i pre> <p>Output:</p> <pre> 1 1 1 2 1 3 2 1 2 2 2 3 3 1 3 2 3 3 </pre> <hr> <h2>C++ Infinitive do-while Loop</h2> <p>In C++, if you pass <strong>true</strong> in the do-while loop, it will be infinitive do-while loop.</p> <pre> do{ //code to be executed }while(true); </pre> <hr> <h2>C++ Infinitive do-while Loop Example</h2> <pre> #include using namespace std; int main() { do{ cout&lt;<\'infinitive do-while loop\'; } while(true); < pre> <p>Output:</p> <pre> Infinitive do-while Loop Infinitive do-while Loop Infinitive do-while Loop Infinitive do-while Loop Infinitive do-while Loop ctrl+c </pre></\'infinitive></pre></i<<\'

C++ Infinitiv do-while loop

I C++, om du klarar Sann i gör-under-slingan blir det infinitiv gör-under-slinga.

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