warning: format '%c' expects type 'int', but argument 2 has type 'char *'

Solution 1
You mean
printf("%c", *currentHex);
In my opinion you can remove the entire idea of currentHex
since it just adds complexity for no value. Simply do:
printf("%c", hex[hexCounter]);
The important point is that you're supposed to pass the value of the character itself, not it's address which is what you're doing.
Solution 2
You have hex[hexCounter]
as a char
so when you set
currentHex = &hex[hexCounter];
you are setting currentHex
to the address of a char
, i.e. a char *
. As such, in your printf
you need
printf("%c",*currentHex);
What you are doing is unnecessary anyway, since you could just do
printf("%c",hex[hexCounter]);

I'm trying to print all characters stored in hex array to the screen, one by one, but I get this strange error in line 16. As far as I know, %c should be expecting a char, not an int. Why I'm getting this error? Below is my code, thanks.
#include <stdio.h> #include <stdlib.h> #include <limits.h> #include <ctype.h> #include <string.h> int main() { char hex[8] = "cf0a441f"; int hexCounter; char *currentHex; for(hexCounter=0; hexCounter<strlen(hex); hexCounter++) { currentHex = &hex[hexCounter]; printf("%c",currentHex); } return 0; }
