txt file and more

composter (21)
so i pretty much ended writing my program and i have 2 questions.
1. i want to make all the cout<< in my program to be printed on both the program itself and in a txt file, and i wanted to ask what is the most efficient way to
do it?
2. well it isn't exactly a question but i would like a feedback on my programming
because i think i'm doing it really bad, like i don't see a reason to use a pointer or an address but i see that everybody using them.
please help me, thank you.

1. i want to make all the cout<< in my program to be printed on both the program itself and in a txt file, and i wanted to ask what is the most efficient way to
do it?
There are several ways to do this. The easiest would be a macro (not so good, but in a small context may be ok):

2
3
4
5
6
 
#define BOUT(expr) cout << expr; fout << expr

...

for(o=0; o<c; o++ ){
        BOUT("rabbit "<< robit[o].name<< " turn"<< endl<<endl);


2. well it isn't exactly a question but i would like a feedback on my programming
because i think i'm doing it really bad, like i don't see a reason to use a pointer or an address but i see that everybody using them.
Pointer (especially raw pointer) should be avoided whenever possible. So an approach without pointer is mostly better, but you shouldn't avoid pointer at all cost...
