C++ do-while loop brukes til å iterere en del av programmet flere ganger. Hvis antall iterasjoner ikke er fast og du må utføre loopen minst én gang, anbefales det å bruke do-while loop.

C++ do-while-løkken kjøres minst én gang fordi tilstanden er sjekket etter loop-teksten.

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

Eksempel på C++ do-while-løkke

La oss se et enkelt eksempel på C++ do-while loop for å skrive ut tabellen med 1.

 #include using namespace std; int main() { int i = 1; do{ cout&lt; <i<<'
'; i++; } while (i <="10)" ; pre> <p>Output:</p> <pre> 1 2 3 4 5 6 7 8 9 10 </pre> <hr> <h2>C++ Nested do-while Loop</h2> <p>In C++, if you use do-while loop inside another do-while loop, it is known as nested do-while loop.

C++ Nested do-while Loop

I C++, hvis du bruker do-while loop inne i en annen do-while loop, er det kjent som nestet do-while loop. Den nestede do-while-løkken utføres fullt ut for hver ytre do-while-løkke.

La oss se et enkelt eksempel på nestet do-while-løkke 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++, hvis du består ekte i do-while-løkken vil det være infinitiv do-while-løkke.

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