Hi
in this statement
FILE *f1;
f1=fopen("123456789.txt","w");
here the pgm should open the named file if it exists or should create a new one right, but it just creates a file with only 8 characters in its name like 12345678.txt. why is it so. also i get an error if i try to open a file whose name is more than 8 chars. i want file with length of name to be opened.what to do
