printitself.c

#include <stdio.h>

int main()
{

char ch;
FILE *file;

file=fopen("printitself.c","r");

while((ch=fgetc(file))!=EOF)
printf("%c",ch);

return 0;
}

Try to google....quine Problem...

one solution is 

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

#include <stdio.h>

static char prog[] = "#include <stdio.h>%c%cstatic char prog[] = %c%s%c;%c%cint main(void)%c{%c    printf(prog, 10, 10, 34, prog, 34, 10, 10, 10, 10, 10, 10, 10);%c    return 0;%c}%c";

int main(void)
{
    printf(prog, 10, 10, 34, prog, 34, 10, 10, 10, 10, 10, 10, 10);
    return 0;
}
