Question

Given the following program segment….

            for (num = 10; num >= 1; num--)

           cout << setw(3) << num;

Write a while loop that will have the same output.

C++

Answer 1

Code:

int num = 10; //Initialization of loop variable
while(num >= 1) //Condition of loop
{
   cout << setw(3) << num; // loop statement
   num--; //Decrement or Increment
}

Explanation: In for loop there is Initialization, Condition and Increment or Decrement. Convert for loop into while loop we need to take care of Initialization, Condition and Increment or Decrement.
