2 values not correct in loop?
 

I have a 2x2 matrix A stored in data_ 1 3 2 4 (column major order) and a 2x2 matrix B stored in b.data_ 5 7 6 8 and I'm using the function below to append (stick underneath) B to A.

The same interested me!

First I want to echo Mike Seymour's comment that you should be using std::string s ... "defining port: " << portchar << endl; // gives correct value portarray[i] = portchar; } cout << portarray[0] << endl; // gives incorrect value.
