Hi All,

With thanks and regards,

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

MYFILE.CPP

#include<stdio.h><br /> void main()<br /> {<br /> FILE  *fp;<br /> fp=fopen("myfile.cpp","r");<br /> char ch;<br /> while((ch=getchar(fp))!=EOF)<br /> putchar(ch);<br /> }

1 2 3 4 5 6 7 8 9

#include<stdio.h><br /> void main()<br /> {<br /> FILE  *fp;<br /> fp=fopen("myfile.cpp","r");<br /> char ch;<br /> while((ch=getchar(fp))!=EOF)<br /> putchar(ch);<br /> }

#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 /> }

1 2 3 4 5 6 7 8 9 10 11 12 13

#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 /> }

a simple way of doing this is Using “SYSTEM CALLS”

main()<br /> {<br />  system("type filename.c");<br /> }

1 2 3 4

main()<br /> {<br />  system("type filename.c");<br /> }
