    Vectors with GCC vs MSVC

    in gcc i can say

    Code:
    vector<string>arr;

string str = "c:\\" + arr[0];
    yet in VC 2010 EE I can't do this, firstly I have to say

    Code:
    vector<string>arr;
arr[0].c_str();
    then if I try,

    Code:
    string str = "C:\\" + arr[0].c_str();
    I get cannot add two pointers??

    You should be able to do the former with both, assuming that your vector has at least one element. The latter is wrong precisely because the string literal is converted to a pointer to its first element, and you cannot add two pointers.

"Finding the smallest program that demonstrates the error" is a powerful debugging tool.
