Program to print source code as program output.

#include

int main(int argc, int *argv[]){

        FILE *fp;

        char ch;

        fp = fopen(__FILE__,"r");

        do{

            ch = fgetc(fp);

            putchar(ch);

        }while(ch != EOF);

        fclose(fp);

        return 0;

}

Output:

#include 

int main(void)
{
 FILE *fp;
 char c;

 fp = fopen(__FILE__, "r");

 do
 {
  c=fgetc(fp);
  putchar(c);
 }
 while(c!=EOF);

 fclose(fp);

 return 0;
}
