Why is it showing no operator= for my vector iterator?

Question

This is the function for computing maximum sum of a subarray ``` int Solution::maxSubArray(const vector &A) { vector::iterator i; int max_so_far = *A.begin(); int current_max = *A.begin(); for(i = A.begin(); i != A.end(); ++i) { current_max = max(*i,*i+current_max); max_so_far = max(max_so_far,current_max) } return max_so_far; ``` } This is the error , I'm getting this for C++11 and not in previous versions. Help me solve this ``` solution.cpp: In member function 'int Solution::maxSubArray(const std::vector&)': solution.cpp:9:8: error: no match for 'operator=' (operand types are 'std::vector::iterator {aka __gnu_cxx::__normal_iterator >}' and 'std::vector::const_iterator {aka __gnu_cxx::__normal_iterator >}') for(i = A.begin(); i != A.end(); ++i) ^ solution.cpp:9:8: note: candidates are: In file included from /usr/include/c++/4.8/bits/stl_algobase.h:67:0, from /usr/include/c++/4.8/bits/char_traits.h:39, from…

Accepted Answer

You need to use `vector::const_iterator` instead of `vector::iterator`. If you are working with a compiler that supports C++11 or later version, you can use `auto` type. ``` auto i = A.begin(); ```
