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 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.

So I have these two variables, a and c, they both have a space after them so when I'm trying to join them it prints "a c " and not "ac". How should I go on about removing the spaces?
set "a=%a: =%"
is one way. set the variable=%variablename:stringtoreplace=replacementstring%
The quotes ensure that any trailing spaces in the set line are not included into the value assigned.
The replacement string may be empty.
This is a general solution, replacing all strings matching stringtoreplace with the defined replacement.

How exactly does Ncurses capture input into the console? I would like to implement it myself instead of using ncurses due to the overhead that ncurses is causing.
Thanks!
Very short and basically: It might use the TTY ioctl calls to get and set flags needed for the different modes. Then it could simply use read to read characters in a blocking or non-blocking manner.
Special keys (like the function keys for example) are read using multiple characters which are parsed.

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 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.
