reading input in from a file

Question

so I'm a newbie at C++, and I've been poking around on the internet on how to do this, and so far I have this:

void includeFile(string name){ ifstream ifs; ifs.open(name); string commands; while (getline(ifs,commands)){ commandReader(ifs); } ifs.close(); }

(commandReader is a function that takes an istream)

When I try to compile, I get the error "no matching function for call" and then gives me the line number for the ifs.open(name) line. I've included fstream, so not sure why it's doing this

In the future, try a reference. Note that there are two overloads of the function and one of them is available in C++11. — Qaz

Sorry, never mind; found the answer right after I posted this. The solution was to have name.c_string() as the parameter instead, as string support was only added in c++11

As @chris pointed out, pre-C++11, ifs.open expects a char*, not an std::string. Try ifs.open(name.c_str()).
