File Names as Input

• A file name is a string

• A string is just a sequence (array) of characters

• In order to read a file name into your program you need a variable that is capable of holding a string

  • char file_name[MAX_NAME_LENGTH+1];
  • This declaration provides an array of characters to store the string in

const int MAX_NAME_LENGTH = 80;

char file_name[MAX_NAME_LENGTH+1];

ifstream in_stream;

cout << “Enter the file name (maximum of “ << MAX_NAME_LENGTH << “ characters):\n”;

cin >> file_name;

cout << “OK, I will edit the file “ << file_name << endl;

in_stream.open(file_name);
