binary output with c++

I've just begun programming in c++ a couple of weeks ago, and i'm trying different things.
But I'm having problems getting a good output in the binary output files, when there is a binary and a non-binary input.
The programm stays in a loop when I execute it.
I don't understand why, so I could realy use some help.

#include <iostream>
#include <fstream>
#include <iomanip>
#include <cstring>
using namespace std;

struct klbstd
{
int klnr;
char klsrt[1];
char klnaam[25];
char kladr[25];
char klpstcd[6];
char klplts[15];
long klbnr;
long klgiro;
char mutcode[1];
char tariefaf[1];
};

const int HIGHVALUE = 99999;

void writeKlantbestand(ofstream& outputFile2, int klnr, char klsrt[], char klnaam[], char kladr[],
char klpstcd[], char klplts[], long klbnr, long klgiro, char mutcode[], char tariefaf[]);
void writeRecord(char best1[]);
void uitvoer(char best1[], char best2[], char best3[], char best4[], char best5[], char best6[]);
void klbnieuw(char best1[], char best4[]);
