Print your own program

Brief # include <stdio. h>

Main () {char * s = "# include <stdio. h> % cmain () {char * s = % c % s % c; printf (s, 10, 34, s, 34) ;}"; printf (s, 10, 34, s, 34 );}

'\ "' Uses a slash

Main () {char * a = "main () {char * a = % c % s % c; printf (a, 34, a, 34 );}"; printf (a, 34, a, 34);} '\ "' uses printf (" % c ", 34); Output

'\ N' can use printf ("% c", 10); Output

 

 

 

Easy to read # include <stdio. h>

Main (){

Char * s = "# include <stdio. h> % cmain () {% c % cchar * s = % c % s % c; % c % cprintf (s, 10, 10, 9, 34, s, 34, 10, 9, 10 ); % c }";

Printf (s, 10, 10, 9, 34, s, 34, 10, 9, 10 );

}

What a fantasy!

Executable files generate their own source files

// Copyright (c) LeafCore

# Include <stdio. h>

Main (){

FILE * fp = fopen ("file. c", "w ");

Char * s = "// Copyright (c) LeafCore % c # include <stdio. h> % cmain () {% c % cFILE * fp = fopen (% cfile. c % c, % cw % c); % c % cchar * s = % c % s % c; % c % cfprintf (fp, s, 10, 10, 9, 34,34, 34,34, 34, s, 34,10, 9,10, 9,10, 9,10); % c % cfclose (fp); % c % creturn 0; % c }";

Fprintf (fp, s, 10, 10, 9, 34, 34, 34, 34, 10, 9, 34, s, 34, 10, 9, 10, 9, 10 );

Fclose (fp );

Return 0;
