Answer 1

What is it are you trying to do?
I see you try to implement sorting algorithm in your code but I also don't understand the output of your code.

If what you want is to simply "write the size of first string in vector" then you can simply do

std::cout << vector[ 0 ].size();

Where <vector> is a vector of std::string.

But looking at your code, I failed to see the connection between the code and your question.

Answer 2

these are some of the mistakes you are making.

for ( int i = 0 ; i < list.size()-1; i++ )

for (auto s : list) result.append(s + ' ' + to_string(s.length()) + "\n" );

or string result[list.size()];

Answer 3

I want to lexicographicaly find the first element in vector, then output this element with a string "***" between each character. For traversing through the length of the element I used to know the size. Somehow I do that, but it seems strange to me. This compiler print it, but particular one reports undefined behavior.
