Code:
int *ptr=5;

Pointer can only be initialized to zero or null if it does not point to a variable of that type.

Code:
char *str="helloworld\n";
printf("string value is %s\n",*str)

The "%s" conversion specification takes a pointer argument not the actual character that *str points to. So if you want to print the entire string...

Code:
printf("string value is %s\n", str);

and if you want to print the character that *str points to...

Code:
printf("str points to %c\n", *str);

Lower ASCII characters.

Hi, I'm writing a BBS telnet program. I'm having issues with it not displaying lower ASCII characters. For example, instead of displaying the "smiley face" character (Ctrl-B), it displays ^B. Is this because i'm using Ncurses? If so, is there any way around this? Thanks. (3 Replies)
