how to print fibbonacci numbers diagonally ....
i have written the code for fibonacci series .. & i am getting the Output ..

Code:

#include<stdio.h>
#include<conio.h>
void main()
{
	int a=0, b=1, c, i, num,j,k;
   clrscr();
   printf("Enter till whr u want fibbo : ");
   scanf("%d",&num);
   printf("\n %d",a);
   printf("\n\t%d",b);
   for(i=1; i<=num; i++)
   {
      c=a+b;
      a=b;
      b=c;
      printf("\n");
      printf("\t");
      for(k=i; k<=i; k++)
      {
	printf("\n\t");
	for(j=i; j<=i; j++)
	{
	  printf("\n\t");
	  printf ("\n\t %d",c);
	  printf("\t");
	  if(i==j)
	  {
	    printf("\t");
	    break;
	  }
	 }
      }
   }
   getch();
}

..This is the Code ...
But i want my output as ......

1
1 1
1 1 2
1 1 2 3
1 1 2 3 5
1 1 2 3 5 8 ... & so on ..

i know that \n is for next line & \t is for TAb space ...
But i want to do this only through loops ...& whenever the counter comes inside any loop it goes to the First position ..

2. I don't think your code actually solves what the OP wanted.

It sure doesn't, which is why I posted it. His code didn't find the correct sequence, let alone display it correctly. Consider it a building block.

The solution that I've written doesn't make use of any tabs.

Since you're tasked with using for loops, I will tell you to use a pair of nested for loops. Now you have to decide what your loop conditions will be for the inner and outer loop.

I would suggest creating the desired sequence first, storing it, and then worrying about displaying it.
