HI all

[Kaushalya]

Wish you all a good day.Currently i'm working on c++ project.I want to know how to convert string object to a character array.Also why ifstream object doesn't accept a string variable as follows,
void split(String filename)
{
ifstream ifile;
ifile.open(filename);//this fails

}

I guess you need to pass filename.c_str() .

A string already is a character array. See this post.

If you want to open a file where filename is a string, you need to use the c_str () function:

ifile.open(filename.c_str ());
