If i am not wrong then cout <<"sum"; just Prints the word "Sum" while cout << sum; prints its value.

Thanks to the lack of parenthesis and curly braces, the code is always much clearer and more readable than C or C++ code!
Example: C++ vs Python
if (x>0)
{ std::cout << "x is positive."
<< std::endl; }
if x>0:
print("x is positive.")
