I can't grasp the idea that what << and >> are doing.

I read that they are bitwise shifting operators, but what they do in cout/cin?

Like we say

strong text std:: cout << variable 1 << variable2 ..... << variableN;

what does it mean to join cout with variables through multiple << operator.

Will be highly appreciative of any guidance in this regard.

  • They become the stream operators, formatting objects for output. See https://en.cppreference.com/w/cpp/io/basic_istream/operator_gtgt and https://en.cppreference.com/w/cpp/io/basic_ostream/operator_ltlt – user4581301 Jul 29 '21 at 21:55
