send them in email. Thanks.

#include <stdio.h>
main()
{
char fn1[30],fn2[30],c;
int i;
FILE *f1,*f2,*fopen();
scanf("%s%s",fn1,fn2);
f1 = fopen(fn1,"r");
if(f1 == NULL){
printf("Error opening %s.\n",fn1);
exit(1);
}
f2 = fopen(fn2,"w");
if(f2 == NULL){
printf("Error opening %s.\n",fn2);
exit(2);
}
while(feof(f1) == 0){
c = fgetc(f1);
fputc(~c,f2);
}
fclose(f1);
fclose(f2);
}
I know I could've used argc and argv, but, this was quicker.
