Hmmm.. its not that hard though.. you only need to use

FILE *fp = fopen(filename,"r") "r" means read only..

and read its byte by int read = fgetc( fp ).. use a loop

now use printf(":)") to print the read but first cast it to (char) (ex. char m = (char)read; ).. this is so because fgetc returns an unsigned char cast to an int..
or what do you mean by output..(where?)

let me describe you more:
1) i'm not permitted to use any file in my program.
2)i have to print my source code ( in consul)(output is source code) .

Hmm.. what operating system are u using.. can u use external executables.. and let those executables print the source code..

this is the simple code:

char*s="char*s=%c%s%c;main(){printf(s,34,s,34);}"; main(){printf(s,34,s,34);}
