Need to read everything until say *** comes up:
Input:
Hey there
how are
you
***
Output:
Hey there
how are
you
Would have used scanf("%[^***]s) but can't read all lines at once.
Only having basic C knowledge
The way I would do this is read one line at a time (with a funcion such as fgets instead of scanf) and then see if the line that you last read is equal to ***. You can use use strcmp to do that but you can also do it by hand if you are not allowed to use strcmp for some reason.

I saw this special macro when I read a source code. If I remember correctly, it is defined in the standard library.
The name of this macro is related to the buffer size, and in my machine its implementation is 1024.
Now I want to use it to initialize the buffer but I forgot what it is called.
So is there any one who can help me make my code look more professional?
If I don't know what I am looking for specifically, how can I clearly say what I need?
Are you talking about BUFSIZ? It's a macro provided by <stdio.h> and it expands to the size of the buffer used by setbuf().
I'm not sure what use it has in your own code.

I want to add two blank space inside c programming print statement. I have try but it always count one single space. How can i add another one ?? If i use \t then it count 4 space as set.
printf("Hello Dhaka!");
printf("Hello Dhaka!"); adds 2 spaces, since it contains 2 spaces.
The problem must be related to your output. Perhaps the console uses some strange font that is not fixed-width.

I just found a short code here, which would detect blank lines in a file. It used fgets() function in C library.
I wonder if character functions are better suited for files which have tabs, and perhaps continous spaces.
My qustion is what is the best way to parse a file for blank lines?
You can also use scanf(" %[^\n]s",string); in order to read spaces but fgets is best solution for your case.

I need to recode the printf function using only a handful of functions from the libc library, namely write, malloc and free and a few other basic ones. The only formatting tab that I am having trouble with is %p as I have no idea how to display it using the write function, as passing the address of my pointer to a function that prints strings resulted in empty output. I have also tried typecasting it to a char * and unsigned char * but that did not work either. I have looked online but only found solutions invloving forbidden functions so I am not even sure where to begin.

In C, is it possible to force an unsigned char to print as a hex, not with %x, but in the little square box that displays the four hex numbers, but only takes up one character, for example 轩?
No, it is not possible.
This is not related to C, but to the font your terminal uses. C outputs characters as bytes; your terminal is responsible for choosing how to display them as pixels. (You might as well ask how to make the text italic.)
