mellemrum giver problemer :S

Kode 

#include <iostream>
#include <stdio.h>
#include <string>
using namespace std;
int main(int a, char *s[])
{
	int j = 0;
	string blaa;
	cin >> blaa;
	char* input = new char[blaa.length()+1];
    strcpy(input, blaa.c_str());
	char fil[] = "EKSEMPEL.TXT";
	FILE *fp;
	if((fp = fopen(fil, "w")) != NULL)
	{
		while(input[j]) putc(input[j++], fp);
		fclose(fp);
		}
	return 0;
}
