Answer 1

#include <iostream.h>
#include <fstream.h>

void main() {
int i;
ofstream outfile("out.dat",ios::out);

for (i=0;i<10;i++) {
outfile << i+1 << "\n";
}
}

C version:

#include <stdio.h>

void main() {
int i;
FILE *outfile;

outfile = fopen("out.dat","w");
for (i=0;i<10;i++) {
fprintf(outfile,"%d\n",i+1);
}
fclose(outfile);
}
