How do I iterate over cin line by line in C++?

Question

I want to iterate over std::cin, line by line, addressing each line as a std::string. Which is better:

string line;
while (getline         


        

Answer 1

The first one.

Both do the same, but the first one is much more readable, plus you get to keep the string variable after the loop is done (in the 2nd option, its enclosed in the for loop scope)
