Program code

  

  
  for(int i=1; i < N; i++)
  {
  a=i+10;
  b=i-5;
  c=a+b;
  }
  
  
  

using SPAN and DIV elements

Elements SPAN and DIV are used for mark-up
SPAN is use dfor marking part of row, DIV is use dfor marking block (bigger paert of page)
Adding these element in page would NOT change anything itself, but can be used for adding styles
