C++ :: Reverse The Output From A Pointer?

Write a C program to read the list from the file and store them in the arrays. Your program should write the list of client's account number, client's name and the client's balance to another file called "newdata.txt" in reversed order and also display them on the screen.

An example of output dialog is shown below

Account Name Balance
800 Stacy 100.10
700 Michael 81.05
600 Dale 1005.30
500 Richard 214.89
400 Stone -45.23
300 White 0.00
200 John 345.67
100 Jones 24.50
--------

This is what I have done so far bellow here....But the only missing part is the reversed order of 'newdata.txt'contents.

#include <stdio.h>
#include <string.h>
#include <stdlib.h>
int main() {
FILE *ifpt,*ofpt;

[code]....
