Does #define work?

Question

Hey, i was wondering, does #define work?
I tried many times to define cin as something else but it doesn't work.
I also code on PC and I use it quite often so that's why I asked.
Can anyome help me?

Answer 1

@MEDO capra
The problem is with your code, not the #define directive.
cin<<x is invalid, it should have been cin>>x.

Thus, replace your #define with this one:
#define in(x) cin>>x

A funny example!

using namespace std;

#define br cout << endl

int main()
{
cout << "MEDO capra was a great guy for ";
br;
cout << "50 years!";
}

Answer 5

#include <iostream>
using namespace std;

#define br cout << endl
#define in(x) cin >> x;

int main()
{
int n = 0;
cout << "MEDO capra was a great guy for ";
br;
cout << "50 years!"; br;
cout << "How many tears?! "; in(n);
cout << "Ahhhh... " << n << " years";
}
