A simple query

I found this puzzle in some book and i dont know the solution. please tell me how to write this program.

The following pyramid should be printed using WHILE LOOP.

First, you'll need to figure out how to describe the shape mathematically. Try coming up with a formula relating the line number to the number of stars on that line.
Then it's just a matter of putting that formula into the while loop, which will be a breeze.

Code:

---

#include <stdio.h>
void main()
{
        int i,j,k,l;
        i=4;
        l=1;

        while(i>=0)
        {
                j=i;
                while(j>0)
                {
                        printf(" ");
                        j--;
                }
       
                k=l;
                while(k>0)
                {
                        printf("*");
                        k--;
                }
                l=l+2;
                i--;
                printf("\n");
        }
}

I am sure the answer cant be this complicated, if anyone has a better code please reply...

That is C. This is the C++ board. Which are you looking for?

I am sorry for posing in wrong board, i am just looking for correct algorithm

Goodness me, that’s way too complicated, lol.

It can be done with 3 integers.

is there any chance of reducing number of while loops

Yes, with two, if you’re happy to use a simple if else statement.
