i am not ab;e to write whole program at this time but i give you the clue that you should use file handling and open your file on which you are writting the program

i think you should use file handling and open the file which you are making it will show your file on compiling the program

#include<stdio.h><br />
main()<br />
{<br />
FILE  *fp;<br />
char ch;<br />
fp=fopen("file_display.c","r"); //here 'file_display.c' may differ<br />
//reads char by char and stores it in 'ch' until the End of File<br />
while((ch=getc(fp))!=EOF)<br />
{<br />
 putchar(ch);<br />
}<br />
fclose(fp);<br />
}

#include<stdio.h>

main()

{

FILE *fp;

char ch;

fp=fopen("file_display.c","r"); //here 'file_display.c' may differ

//reads char by char and stores it in 'ch' until the End of File

while((ch=getc(fp))!=EOF)

{

putchar(ch);

}

fclose(fp);

}

a simple way of doing this is Using “SYSTEM CALLS”
main() { system("type filename.c"); }
