A program that produces its source code as output
Can anyone think about a program in any programming language of your choice which will post its own source code as output?

sauravgoswamiwell its possible to write a programme to generate source codes,and it is possible here too,but the challenge is to generate codes according to the need of the hour,say less memory space,more sturdy,preference of tools so.on...

sriramchandrkThere are 3 types of executable programs (interpreted(basic, perl) , compiled programs (c, pascal) & semi interpreted (java) )
You can produce its own source code as output only in interpreted programs.
its possible for semi interpreted using a process called as decompilation but the output may not be exactly same as initial source.
It not possible for compiled program.
example for interpreted program using perl.
=========================
#!/usr/bin/perl
open(INFILE, $0);
while()
{
print "$_";
}
=========================
Thanks & Regards

aashu_itdudethis c++ code reads the source file and displays the code as output. Its not a perfect code for this query but it can be further developed.
#include
#include
#include
#include
void main()
{
clrscr();
int c=0;
char a[238];
ifstream fin("out.cpp"); //name of program
while(!fin.eof())
{
fin.read(a,238);
}
puts(a);
getch();

emYthAssuming that the source file names test.cpp
#include
#include using namespace std; int main() { freopen("test.cpp","rt",stdin); string g; while(getline(cin,g)&&cin) { cout< -

import java.io.*; class Source { public static void main(String args[])throws IOException { FileReader fr=new FileReader("Source.java"); int c; while((c=fr.read())!=-1) { System.out.print((char)c); } } }

I think try it by using the same file name in that program. open the same file read it and then print it. just try it.prakash.athaniCan anyone think about it and post replies? -

int main(void)
{
printf(s,10,34,s,34,10,10);
