File input question from a newbie
What I'm trying to do is read a simple text file in then encyrpt it,
for example A will become M, B becomes N, etc, this will be the output. But I can't get it to actually read the file.
The encyrption works fine, if I just prompt the user to manually enter the text, removing the file opening code.
Thanks for any help you can give me.
Code:
#include <stdio.h>
FILE *fp;
fp=fopen("c:\Documents and Settings\Mckinstry_MaL\Desktop\My-Projects\cipher.txt", "r");
int
main( void )
{
int ch;
while( (ch = getchar()) != EOF ){
if( ch >= 'A' && ch <= 'Z' )
ch += 13 ;
putchar( ch ):
}
}
