[Solved] OUTPUT ERROR,The problem is to find the sum 5000 digit number cpp [closed]

I don’t understand why you are using std::vector. You could calculate the sum without using the vector:

int k=0,sum=0;
for(int i=0;i<s.length();i++)
{
    k = s[i]-'0';
    sum += k;
}

Note: if you are a little paranoid of the sum value fitting into an integer, you can use an unsigned integer since digits can’t be negative.
