I'm refreshing my C/C++ skills and have encountered something that's stumped me. Dunno why it does this...
I open a .txt file I made with MsDos Editor in my program and use cout to show it. Instead of showing all the text in there, it shows a hex string (0x77fd44). Anybody know why this is?

you are outputting the fileobject to cout instead of it's contents.

try this:

Code:

#include <iostream>

#include <string>

#include <fstream>

using namespace std;



int main()

{

 *cout<<"Which file do you want to open?" << endl;

 *string name;

 *cin >> name;

 *cout << "Opening "<< name << "..." << endl;

 *ifstream file (name.c_str());

 *cout << file.rdbuf();

 *cin.get();

 *return 0;

}

Yup, noticed. I added a do-while loop that takes a line, puts it in a string and couts that, and that till the line's "". Might be buggy when the text looks like this:

Code:

Hello,



My name is Bob.



I like cheese.

with file exists check:

Code:

#include <iostream>

#include <string>

#include <fstream>

using namespace std;



int main()

{

 *cout<<"Which file do you want to open?" << endl;

 *string name;

 *cin >> name;

 *cout << "Opening "<< name << "..." << endl;

 *ifstream file (name.c_str());

 *if(!file) {

 * * cout <<"file: "<< name << " doesn't exist" <<endl;

 * * return 1;

 *}



 *cout << file.rdbuf();

 *cin.get();

 *return 0;

}
