GNU Indent – beautify C code !!

Wanna beautify your C program without having to go through the hassle of manual Indentation of the code??

Then The GNU Indent program is here to make your work easy 🙂 ….

The GNU Intend program changes the appearance of a C program by inserting or deleting white space .

>>First Step – Installing Indent on your GNU/Linux system (in my case its ubuntu)

Go to Terminal and issue the following command

$ sudo apt-get install indent

Now intend is installed ..

>>Second Step – Writing a simple piece of unindented code using your favorite editor ( in my case gedit )

$ gedit howdy.c

#include <stdio.h>
int main()
{
printf ("This is a demo of GNU Indent\n");
return 0;
}

>>Third Step – Indenting!!

$ indent howdy.c

Now open the file howdy.c

$ cat howdy.c
#include <stdio.h>

Int
main ()
{
 printf ("This is a demo of GNU Indent\n");
 return 0;
}

Now the program has been properly indented …if u wanna see the previous version of the program then use the command

$ cat howdy.c~

This tool is a very powerful one…. more about its abilities in the coming posts 🙂
