Use of auto keyword

#1

I was watching the first lecture on string class.
I have a doubt that while using iterators to iterate over all the characters of a string, what was the use of “auto” keyword in the for loop bracket. what does it mean?

#2

hello @priyam04

auto is a keyword in c++ that detects the datatype of data automatically.

for example

for(char  x : stringName) {


} 
``
here in place of using char u can use auto , it will deduce its type on its own
