Use ident to format your C program

This site mentioned the Linux tool indent and tried it for a while. It is really easy to use. To sum up, I hope it will help readers.

 

 Download and install:

1. For Linux (Fedora) users, the simplest installation method is "yum install indent"

2. Windows
You can download the package from http://gnuwin32.sourceforge.net/packages/indent.htm.

 

Usage:

For more information, see http://www.worldhello.net/doc/program_rules/indent.html.

I tried it several times and found that the parameter "-I4-bli0-ut-ts4" is my favorite style.

 

How to format files in batches (my own script has been verified)

1. Windows users:

1. Enter the source code root directory you need To Format

2. Save the following content as indent_my_prg.bat

3. Run indent_my_prg.bat

 

@ Echo off

Setlocal enabledelayedexpansion

Dir *. C/S/B> c_list.txt

For/F "tokens = 1 * delims =" % A in ('findstr. c_list.txt ') Do (

: Echo %

Set AA = %

Indent-I4-bli0-ut-ts4! Aa !)

 

1. Linux users:

1. Enter the source code root directory you need To Format

2. Save the content under ------- as indent_my_prg_in.sh.

3. Run indent_my_prg_in.sh.

 

@ Echo off

Setlocal enabledelayedexpansion

Dir *. C/S/B> c_list.txt

For/F "tokens = 1 * delims =" % A in ('findstr. c_list.txt ') Do (

: Echo %

Set AA = %

Indent-I4-bli0-ut-ts4! Aa !)

 

What kind of code can indent arrange? The following is an example. The following shows a program that can calculate the factorial of A large number due to abnormal formats.

 

# Define n 100

Int A [n * 5] = {1}, n = N, I, C, M = 1; Main () {for (; n --) {for (C = I = 0; I <M | C;) A [I ++] = (C + = A [I] * n) % 10, c/= 10; M = I;} For (; m;) putch (A [-- m] + 48 );}

 

Below is the code after the format is rearranged. Isn't it nice.

 

#define N 100

int a[N * 5] = { 1 }, n = N, i, c, m = 1;

main ()

{

        for (; n; n--)

        {

                  for (c = i = 0; i < m || c;)

                           a[i++] = (c += a[i] * n) % 10, c /= 10;

                  m = i;

        }

        for (; m;)

                  putch (a[--m] + 48);

}
