string manipulation

How do i get the contents of a file into a buffer so that i can use some <string> functions on it?

Cheers

Sorry i wasn't to clear, i know how to ge a file into a buffer but i want to convert it from (const * char) to (string) but i don't know how to.

I hope that makes sence.

I think the fstream's getline() function can have a string as the output parameter (CMIIW). Or why don't you use the copy constructor of the string? E.g.

Code:

 char str1[]="Hello World!";
 std::string str2=str1;

If you want to read the entire contents of a file into a string object you can use a stringstream as an intermediate object.

Code:

ifstream file("foo.txt");
stringstream sstr;
string info;

if( file.is_open() )
{
    sstr << file.rdbuf();  // Read entire file into stringstream
    info = sstr.str();     // Convert stringstream into string
    // Do whatever you want with the string "info".
}
