GMP gmp_printf()
===

I've just started messing with GMP and I can't seem to get numbers to print properly. Here is what I'm trying:

    #include <stdio.h>
    #include <stdlib.h>
    #include "gmp.h"
    int main(){
      mpz_t  n;
      mpz_init (n);
      mpz_set_ui(n, 2);
  
      gmp_printf("attempt 1: %d \n", n);
      gmp_printf("attempt 2: %Z \n", n);

      return 0;
    }

I know this must be something really simple... but I'm just not seeing it.

My output is: 


    attempt 1: 1606416528 
    attempt 2: Z 

I think I might just be using mpz_set_ui wrong...
