  1. Programming do-while Loops

  2. The do-while Statement • Syntax doaction while(condition) • How it works: • execute action • if condition is true then execute action again • repeat this process until condition evaluates to false. • action is either a single statement or a group of statements within braces. action condition true false

  3. N! int number, factorial, counter; cout << "Enter a positive integer:"; cin >> number; factorial = 1; counter = 1; do{ factorial *= counter; counter++; }while(counter <= number); cout << "The factorial of " << number << " is " << factorial << endl;

  4. 2N int number, result, counter; cout << "Enter a positive integer:"; cin >> number; result = 1; counter = 1; do{ result *= 2; counter++; }while (counter <= number); cout << "Two raised to the " << number << " power is " << result << endl;

  5. Maximum int value; // input value int max=0; // maximum value do{ cout << "Enter a positive number “ << "(-1 to stop):"; cin >> value; if(value > max) max = value; }while(value!=-1); cout << "The maximum value found is " << max << endl;

  6. Waiting for a Reply char reply; do{ // do something cout << "Continue(y/n): "; cin >> reply; }while(reply!='n');
