write this program and save it as pro.c....run....it will show the program to the consol and write the source code into data.txt file...................

#include<stdio.h>
void main()
{
 FILE *fp,*ft;
 char buff[100];
 fp=fopen("pro.c","r");
 if(fp==NULL)
 {
  printf("ERROR");
 }
 ft=fopen("data.txt","w+");
 if(ft==NULL)
 {
  printf("ERROR");
 }
 while(getc(fp)!=EOF)
 {
  
  fscanf(fp,"%s",buff);
  printf("%s\n",buff);
  fprintf(ft,"%s\n",buff);
 }
}

A program that produces its complete source code as its only output is called a quine.

Eg:

char*f="char*f=%c%s%c;main()
printf(f,34,f,34,10);%c";
main()printf(f,34,f,34,10);
