File I/o Problem In C/c++

[Kon-Tiki]

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?

It's starting to come back to me... am fixing it now :bye:

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

try this:


#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:

Hello,

My name is Bob.

I like cheese.

with file exists check:


#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;
}
