What data type auto is

#1

I could not understand this line of code

for (auto it = s.begin(); it != s.end(); it++)
{
cout << (*it) << “,”;
}

hello @udatta

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

here s.begin() returns an iterator but we dont want to explicitly write its datatype so we have used auto keyword.
