C :: How To Count Total Number Of Unique Elements In Array
Mar 19, 2013How can i count the total no of unique elements in an array? Like I have an array.
Code:
int array[]= { 2,1,4,0,3,3,0,0,1,2,1,1}
// As it has 0,1,2,3,4 as unique values so total no of unique values are=5
int unique =5;

Jun 29, 2014Acyclic visitor pattern used here to count the number of elements of a certain type in a container.
struct A {
struct Visitor {
virtual ~Visitor() = default;
};
virtual void accept (A::Visitor&) = 0;
[Code] ....
Give the correct:
count = 3
But it is scrappy. The visitor classes had to be placed outside the classes they belonged to, and CountB lost its template because of that. Also, it is very awkward that I have to construct a "reverse hierarchy" for the Visitor classes (which means that this has to bechanged if I ever change the hierarchy for A, B, C, ...). How to improve my solution (using acyclic visitor pattern)? Forward declaring nested classes is not possible in c++.

C :: Check Number Of Elements In Array
Apr 7, 2014I can have at most 3 structs in array, but it could be 0,1,2 or 3 structs in array. I am trying to avoid dynamic memory allocation. I initialize sensors to 3 to reserve space for them in memory, since there may be at most 3 elements in the array. But I am testing a condition where there will only be 2 elements:
Code:
#include <stdio.h>#include <stdlib.h>
#include <string.h>
typedef struct {
unsigned long long int address;
float current;
unsigned char pressure_units;
} sensor;
[Code]...
The problem is even though there are only 2 sensors out of 3 in the array, sizeof(sensors)/sizeof(sensors[0]) returns 3. I assume because when it allocates memory for 3, it includes that allocated memory even though it really doesn't contain the struct. How can I figure out how many elements were really inserted into array, not just allocated to array?
C/C++ :: Array In Class Without Number Of Elements
Apr 10, 2014Is it possible to have array in class without number of elements, for example: I have a class called Plane with number of motors, and string array of passengers, but I don't have a number of passengers, but then again I have it in constructor, so can i print the list of passengers without having the number as part of the class.
Class Plane

C++ :: Random Number Generator - Count How Many Times Each Number Shows Up
Sep 26, 2012I'm running a game online and designing a program to generate Enemy Stats. Basically, it's supposed to generate 25 numbers between 0 and 7(to represent 8 Attributes on a 25 Point Buy system) and count how many times each number shows up.
Here's what the code looks like:

#include <iostream>

using namespace std;
int Generate() {
int r= rand();
int s= r%7;

C :: Why Program Can't Subtract Negative Number From Positive One
Feb 2, 2015My program uses a while loop to eventually get to an error of zero and a root of sqrt(3). I'm not understand why after the third iteration the program fails to compute a new x value. I'm using Visual Studio 2013. The code tag instructions were dubious.

#include <math.h>
main() {
/*This program uses the Newton-Raphson method to solve y = (x^3)-3 for it's roots.*/

C++ :: Input From User A Positive Number N And Find Its Factorial
Oct 8, 2014Write a C++ program that will input from the user a positive number n and find its factorial. Don’t forget to validate the input. The factorial of a positive integer n (denoted by n!) is defines as the product of the integers from 1 to n.
n! = 1* 2 * 3 * ... * (n - 1) * n
You should allow the user to continue working with your program for additional data sets.
Sample output:
Please enter a number: 5
5! = 120
Would you like to continue (Y/N)?Y
Please enter a number: 3
3! = 6
Would you like to continue (Y/N)?N
Good Bye!!
