Write a c program which produces its own source code as its output

How do you write a program which produces its own source code as its output in c language?

#include<stdio.h>

int main(){

    FILE *fp;

    char c;

    fp = fopen(__FILE__,"r");

 

    do{

         c= getc(fp);

         putchar(c);

    }

    while(c!=EOF);

    fclose(fp);

   

    return 0;

}

Output:

#include<stdio.h>

int main(){

    FILE *fp;

    char c;

    fp = fopen(__FILE__,"r");

 

    do{

         c= getc(fp);

         putchar(c);

    }

    while(c!=EOF);

    fclose(fp);

   

    return 0;

}
