fgetc() and TABS, Extended ASCII

Hi all,

I am reading characters from a file input stream and printing out their 1. ASCII value or control mnemonic 2. Binary Value 3. Hexidecimal Value.

My problem is if the the current character I am reading in and then outputing is a TAB it prints an actual tab to screen. I would like instead to be able to print "TAB" for example.

FILE *fp;
inchar = fgetc(fp)

printf("%x",inchar);

etc.

Any help would be appreciated.

Code:

if (inchar == '\t')
  printf("TAB");
else
  printf("%x", inchar);

By control mnemonic do you mean STX, TAB, ESC, etc? You need to create a string array for all the characters below 0x20

Code:

char *CtrlArray[] = {"NUL", ... ,"BKSP", "TAB", ... };

and during your loop, do something similar to what Thantos suggested:

Code:

if (inchar <  ' ')
  printf("%s", CtrlArray[inchar]);
else
  printf("%x", inchar);
