Saving and Opening files (C++)

I need to be able to save and open files for a simple boot-up text editor. Can someone tell me how to use the header files ifstream.h and ofstream.h ?

Here's a simple tutorial from GameDev,

Hope it helps!:)

<fstream.h> is deprecated. Use <fstream>

C-Style:

PHP Code:

---


#include <stdio.h>

int load(char* sz)
{
 char szBuffer[1024]; 
FILE* f = fopen(sz, "r");
 
if(!f)
return -1;

while(fgets(szBuffer, 1024, f))
{
 printf("%s\n", szBuffer);
}

fclose(f);

return 0;

}

int save(char* sz, char* szSave)
{

FILE* f = fopen(sz, "r");
 
if(!f)
return -1;

fprintf(f, szSave);

fclose(f);

return 0;
}

but he was asking for C++:

Code:

---

#include <iostream>
#include <fstream>
#include <string>
using namespace std;

int main()
{
        ifstream in("input.txt");
        ofstream out("output.txt");
        string str;
        char c = in.get();

        while(c != EOF)
        {
                str += c;
                cout << c;
                out.put(c);
                c = in.get();
        }

        cout << endl;

        cout << str << endl;

        return 0;
}
