            [3] = { .age = 41,
                    .name = "Ash",  
                  },
            [1] = { .age = 52,
                    .name = "Axel",
                  }
   };
   
   for (int i = 0; i < 4; i++)
   { 
        printf("users[%d].age = %.1f users[%d].name = %s\n", i, users[i].age, i, users[i].name);
   }
  
   return 0;
}
    
/*

users[0].age = 0.0 users[0].name =
users[1].age = 52.0 users[1].name = Axel
users[2].age = 0.0 users[2].name =
