" string : : iterator it ; " …this means ’ it ’ is an object of class iterator which is in class string ???
(1.) when i write auto it = p.begin() … then ‘it’ automatically becomes integer ???
(2.) par agr hum string : : iterator it = p.begin() ese likhe…tab humne uska data type ‘iterator’ bataya.
Difference kya h 1 and 2 me ???
