ASCII Display

Hi have got to write a program to display a text file within UNIX very much the same as the cat function.
One of the problems is to display the ASCII control characters that's is the the text printable form for example tab represented as \t.
I have managed to just print it out without the control characters but am lost for ideas for how to attack this bit.

Any ideas PLEASE!

if u encounter /t then print it as printf("\t"); it will do fine.

i need it to dispaly the ASCII control characters. Where at the moment i have:

ch = fgetc(in_file);
if (ch != EOF)
putchar(ch);


where ch is an int, and in_file is a FILE.
Displays the text as it is to be shown not the control characters.

You could use a switch() statement to check the contents of ch, and if it's below a certain ASCII character value print something else instead ;)

That will print a tab. You want printf("\\t"); to display \t

Don't you think that ch should be a charecter type for accessing the text.

One more thing i wanna add INSTEAD of using "if" use "while" because i don't think that above mentioned loop will work more than once or Use the "CONTINUE" with "if"

No. It should be an int, because EOF won't work correctly if you try to smash it into a char.


Quzah.
