string a = "A";
string b = "B";
string c = a + b;
string d = "D" + a;
string e = a + "D";
string f = "F" + "F";
Why is the last line not something the string class can handle if it can handle cases a, d, and e?
line 73: Error: The operation "const char* + const char*" is illegal.
(Also, is this something that I could add myself? By developing another + operator for string?)
