Inserting break tag in a StringBuilder

[N Naresh]

hi i want to insert a <br> in StringBuilder after certain number of characters
suppose if the StringBuilder is like ABCDEFGHIJKLMNOPQRSTUVWXYZABCDEFGHIJKLMNOPQRSTUVWXYZ

how i can write the logic to insert <br> at more than one place in above StringBuilder content

You've already been given an example of how to do something like that here

[Bill Shirley]

after you insert "<br/>" at location N,
keep scanning the string for the need for more at index N+ (length of "<br/>")
until you get to the end,
