Ich habe folgendes Program:

#include <stdio.h>
#include <string>
#include<iostream>

}
vector<string> readlist (char *begin){
vector<string>foo_r;
string end=".c";
string all = begin + end;
char *next_r = &all.at(0);
is.open(next_r,ios::in);
if (is.is_open())
{
is.seekg (0, ios::end);
int length_r = 0;
length_r = is.tellg();
is.seekg (0, ios::beg);
char *buffer_r = new char[length_r];
is.read (buffer_r,length_r);
is.close();
foo_r.push_back(buffer_r);
return (foo_r);
}else{
is.close();
off.open(next_r,ios::out|ios::app);
