if(fp1=NULL)

You're setting fp1 to NULL, it should be:

if(fp1==NULL)

Where's your question?
Furthermore, this is a forum for the C language, and you are showing us an aberration of C++.

Use proper code tags when posting source code. Read the rules or you'll be ignored.

O.K... Sorry for not being clear... I will read the rules.

Thanks for alerting me...

You are doing a bit mistake over here...........
fprintf(fp1,"%d\n",&numbers);
please don't give '&' before 'numbers'
if u still face problem then just see my program

#include<stdio.h>

void main()
{
	FILE *p,*p1,*p2;
	int arr[]={1,2,3,4,5,6,7,8,9},i;
	p=fopen("Raj.txt","w");
	for(i=0;i<9;i++)
	{
		printf("%d\n",arr[i]);
		fprintf(p,"%d\n",arr[i]);
	}
	fclose(p);
	p1=fopen("Raj.txt","r");
	for(i=0;i<9;i++)
	{
		fscanf(p1,"%d",&arr[i]);
		printf("%d\n",arr[i]);
	}
	fclose(p1);
	p2=fopen("RajCopy.txt","w");
	for(i=0;i<9;i++)
	{
		fprintf(p2,"%d\n",arr[i]);
	}
	fclose(p2);
}
