File Handling in c Writing to a file
Now to write to a file we have to obviously create a file and then open it in write mode. This can be done by a single statement which is given below
fs=fopen(�abc.txt�,�w�);
Now you may be thinking what the about statement must be doing.
Your answer is right here:
WHAT DOES THE ABOVE STATEMENT DOES?
The above statement does following things:
1. It creates a new file abc.txt
2. It opens the file in write mode.
Now let�s take a look at a small program.
Example:
Writing the content of file from �abc.txt� to �xyz.txt�.
Writing the content of file from �abc.txt� to �xyz.txt�.
#include<stdio.h>
#include<conio.h>
void main()
{
FILE *fp,*ft;
char ch;
fp=fopen(�abc.txt�,�r�);
if(fs==NULL)
{
puts(�can�t open source file�);
exit(1);
}
ft=fopen(�xyz.txt�,�w�);
if(ft==NULL)
{
puts(�can�t open target file�);
exit(2);
}
while(1)
{
Ch=fgetc(fp);
If(ch==EOF)
{
break;
}
else
fputc(ch,ft);
}
fclose(fp);
fclose(ft);
}
