i started to make a program to copy contents from one file to another charcter by character. i made the prog but it is not working..
can u plz tell me the error in the code..?
my code is

#include <stdio.h>
 
main()
 
{
 
char a;
 
 
FILE *fi, *fo;
 
 
fi= fopen ("sohil", "r");
 
fo= fopen ("ab.c", "w");
 
while (1)
 
    {
 
    fscanf (fi, "&c", &a);
 
    if (a==EOF)
 
            {
 
         break;
 
            }
 
    else
 
        {    
 
        fprintf (fo, "%c", a);
 
        }

fclose (fi);
 
fclose (fo);
 
}

I would recommend doing it this way:
1- Open Files. The original and the copy.
2- Declare a character var.
3- Using fgetc() and fwrite() copy content from one to the other
4- close files and you are done.

If this does not get banned, i will post my idea.

#include libraries //don't remember which ones

main(){
char a;
FILE *first,*second;
first=fopen("First.txt","r");
second=fopen("Second.txt","w");
while(!feof(first)){
a=fgetc(first);
fwrite(&a,1,1,second);
}
}

Changed title.
Please use a more problem specific title.

fwrite(&a,1,1,file);
The first parameter is what to be written
The second One is how many bytes are needed for it. Remember a character is a byte, so if you want to write "hello" you have to write 5, otherwise it will split your word. If you write a higher number you will see unexpected characters. The third parameter is how many times you want to write the specified text. The last is the file you want to write in

Remember to write & before your variable or string.
If you want to write a fixed string like "hello" all the times, you have
to write the word between quotes (").
fwrite(&filecontent,5,1,file);
fwrite("Hello World",11,1,file);

Hope this helps!
