[SOLVED] Is that possible by only using while loop?

Is that possible by only using while loop?

My tutor gave me an assignment where I have to write a code that only contains while loop and prints:

I tried it 100 times and failed 100 times. Due to my limited knowledge, I began to think that my tutor is just messing with my brain. If it's possible, please introduce me a code that prints the numbers in that order. Thanks...

Solution

    int i = 1;
    int LIMIT = 5;
    while (i <= LIMIT)
    {
        int j = 1;
        while (j <= LIMIT -i)   //Loop to print the desired space.
        {
            cout << " ";
            j++;
        }
        int k = i;             
        while(k)
        {
            cout<<k;               //Printing the digits
            k--;
        }
        cout << endl;         //Adding new line character at the end.
        i++;
    }

Say hello to your tutor :)
