File Handling in C

[livesinabox]

#include<stdio.h>
#include<string.h>
main()
{
FILE *f1,*f2;
char str[10];
f1=fopen("file1.dat","w");
printf("Enter contents of file 1 :");
gets(str);
fputs(str,f1);
fclose(f1);
f1=fopen("file1.dat","r");
f2=fopen("file2.dat","w");
fputs(str,f2);

fclose(f1);
fclose(f2);
printf("Contents of copied file is :");
f2=fopen("file2.dat","r");
printf("%s \n",str);
fclose(f2);
}

In the above coding I am supposed to be coping contents of File1.dat to File2.dat.

I am new to this and hence when I was given this coding I tried understanding it. From what I can see, I am accepting a string str from the user and inserting it into File1. And then I am using the same variable "str" to insert content into file2. In this process I am not copying contents of file1 into file2. I am basically inserting the same string into file2. And that doesn't serve the purpose of the question. Am I right?

Your analysis is correct. This program does not copy file1 into file2.

By the way, line 9 is very dangerous. Terrible things will happen if the user types more than nine characters.

Thank you for you're help!
And yes I was warned against using the gets function.. I changed it to scanf! Thank you!

Instead of scanf u should use fgets(). Scanf will not do array boundry check and will terminate reading at first space.
