    Make user directory a variable?

    Im trying to make it so that the user can enter the directory of a file and that this file will be read, the problem is i can seem to get the program to use a variable as the directory, this is roughly what i want to happen, with the users directory as 'direc'

    	cout<<"Please Enter the Directory to your Binary File e.g. c:/Documents/file.dat:\n";
    	cout<<"The Directory you entered was "<<direc<<" is this correct? (y or n)\n";
    	while (answer==n) 
    	ifstream file(direc, ios::in|ios::binary);
    So is this possible? any hints?

    >any hints?
    #include <fstream>
    #include <iostream>
    #include <string>
    int main()
      std::string path;
      std::cout<<"Enter the path of your file: ";
      if ( getline ( std::cin, path ) ) {
        std::ifstream in ( path.c_str(), std::ios::binary );
        if ( in ) {
          char ch;
          while ( in.get ( ch ) )
            std::cout<< int ( ch ) <<'\n';
    My best code is written with the delete key.

    It's been called many things, but... "Directory"?

    On a side note, your input method is certainly annoying. I don't often get asked for "confirmation" when I try to open a file through some dialog...
    #include <stdio.h>
    void J(char*a){int f,i=0,c='1';for(;a[i]!='0';++i)if(i==81){
    /3*3+f/3*9+f%3]==c||a[i%9+f*9]==c||a[i-i%9+f]==c)goto e;a[i]=c;J(a);a[i]
    ='0';e:;}}int main(int c,char**v){int t=0;if(c>1){for(;v[1][
    t];++t);if(t==81){J(v[1]);return 0;}}puts("sudoku [0-9]{81}");return 1;}
