There are a lot of ways you can do that :)
Really...
You can just look at you environment:
#echo $LOGNAME (bash)
%echo $user (t?csh)

Things like:
id -p | grep login

...
Well, I said, there are a lot of ways...
Even:
cat << lol > buh.c
#include <stdio.h>
#include <sys/param.h>
int main(void){
    printf("%s\n",getlogin());
    return 0;
}
lol

must work
