Opening A Text File with a variable argument

paulmcco (86)
I'd like to take in a string from the user and open a text file based on the user input: Here's What I have:

1
2
3
4
5
6
7
8
9
10
11
12
13
 
void open(std::vector<std::string> existing_files, std::string name){
			std::string address("C:/Documents and Settings/Lauren/My Documents/Visual Studio 2008/Projects/Marketing/Marketing/Marketing/"+name+".txt");
			const char * choice;

			choice = new const char[address.size()+1];
			strcpy(choice, address.c_str());
			std::cout << choice << std::endl;
			std::ifstream data(choice);
			if(data.is_open()){
			     std::cout << "Hello" << std::endl;
			     std::cin >> num;
			}
		};




The problem is that I cannot modify a const char (variable)...ifstream requires a const char as its main argument. How do I convert the string 'address' to an argument that can be used by ifstream?

why don't you use address.c_str() which returns const char*pointed by string object.
