C :: How To Count Total Number Of Unique Elements In Array

Mar 19, 2013

How 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;

C++ :: Acyclic Visitor Pattern - Count Number Of Elements Of Certain Type In Container

Jun 29, 2014

Acyclic 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++ :: Dynamic Massive - Multiplication Of Positive Matrix Elements

Oct 5, 2014

I have a problem with dynamic massive. My task was to find the multiplication of positive matrix elements with using indexes and seperated compiling.

Compiler doesn't warn me about any mistake, but result is not right, it is even not a number.

Header.h

#include <iostream>
#include <math.h>
using namespace std;
float multi(int k, int t, float **p);

C :: Check Number Of Elements In Array

Apr 7, 2014

I 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, 2014

Is 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
{
private:
int motors; //number of motors

In this program what i'm doing is to search for a number when the vector is in order, and count how many times that number appears, the problem is that count how many times the number does not appear, but when its appear the program stays in an "standby mode" and the cursor does not move.

C++ :: Random Number Generator - Count How Many Times Each Number Shows Up

Sep 26, 2012

I'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:

Code:
#include <iostream>
#include <ctime>
#include <cstdlib>
using namespace std;
int Generate() {
int r= rand();
int s= r%7;
[Code] ....

And here's two outputs.

1: Code:

2: Code:

C :: Why Program Can't Subtract Negative Number From Positive One

Feb 2, 2015

My 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.

Code:

#include <stdio.h>
#include <math.h>
main() {
/*This program uses the Newton-Raphson method to solve y = (x^3)-3 for it's roots.*/
printf("This program uses the Newton-Raphson method to solve y = (x^3)-3 for it's roots. Enter your estimate of the root.
");
float x,y,z;
int num;
num = 0;

C++ :: Input From User A Positive Number N And Find Its Factorial

Oct 8, 2014

Write 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!!

My code for what i think I'm doing is as follows:

#include <iostream>
using namespace std;
int main(){
int i=1;
int n;

C++ :: If Statement To Read Number Negative Or Positive Not Working

#include <stdio.h>
#include <iostream>
#include <iomanip>

PS: I am using char over int because the program that I am testing for requires me to use 8 bit variable.
