tell me, is while(T[l]<p & l<=r) the same as while((T[l]<p)&&(l<=r))

1. As long as K&R precedences still hold you don't need the inner
parentheses; '<' and '<=' has higher precedence than '&' and '&&'.
2. In this case where you compare predicate expressions that
evaluate to '0' and '1' on both sides of '&' and '&&' respectively
these expressions are (while not the same) equivalent _here_. If
you don't want to operate on bits but want to express a boolean
conjunction you should use '&&', though.

i was unable ro remember that

You could look that up if you cannot remember that. Wikipedia[*]
has a page with a lot information, and a concise list you can,
for example, find here:
