I can do it with many "for loops" but how to code it with 2 or three loops(it can be any loop).?I kindly request you give the LOGIC  or CODING for it?

Answer
Hi, Sathish.

Use two for loops, nested within one another.  The outer for loop will contain the number you're counting up to and will decrement every time.  The inner for loop will actually count up from 1 to the desired number and will increment every time.  Something like:

   for (int i = 10; i > 0; --i)
   {
       for (int j = 1; j < i; ++j)
       {
           // print out here
       }
   }

Expertise

I've been programming in one form or another since my brother taught me BASIC when I was 6. I've been programing professionally since I was 20, first web development with HTML, JS, DHTML, CSS, etc., then I became a video game developer, writing code in C, C++, C#, SQL, assembly, and various scripting languages. I've even written my own scripting languages, custom designed for the games I was making. I also dabble in Java, PHP, and Perl. I've worked on pretty much every aspect of game development, including graphics, audio, gameplay, tool, UI, input, animation, and physics.

Experience

I've been writing C code for 12 years, both on my own in my spare time and professionally.
