C++ :: Adding Arrays And Matrix To A Class?

Feb 5, 2014

I'd like to start out by adding an array to a C++ class. I'd like to be able to reference the array using a class object that I create, for example:

Class is Stone.

Stone Bob is an instance of "stone" that I name "Bob".

"Bob.array[1] = "granite";" tells the compiler that the second element in the array (with the first being the zeroth element) is a string containing "granite".

I'll eventually want to extend this to an n x m matrix within the "stone" class that can be referenced as: Bob.matrix[1][3]="lignite";

I tried to make this work using a text again and again last night to no avail. My code is below.

NOTE: Since I am dynamically allocating memory space, I'd like to avoid memory leaks when using this class with dynamically allocated arrays and matrices. Not sure how to do this. Also need some insight into "destructor", and why my simple version reduced to a comment below doesn't seem to please the compiler.

CODE FOLLOWS:

Code:
// AINOW.cpp : Defines the entry point for the console application.
//
#include "stdafx.h"
#include <iostream>
#include <string>
using std:: string;
using std:: cout;
using std:: endl;
using std:: cin;

C++ :: Function Returns Values After Loop Done

May 15, 2013

I am writing a program with a function that includes a long loop. I need this function to return a value when each loop is done, to send this value to output, in order to follow the progression. But I don't know how to do it in easy way. The function is like follow:

int goC(){
... // some local value definition
for(int i = 0; i < 1000; i++){
... // a lot of calculations done here
return i; // -> return the value after each loop is done
}
}

Here it only returns one value, i = 0. Clearly it's wrong.

C++ :: Comparing Arrays To Have Same Elements

Sep 2, 2014

If I have 2 arrays, say array1 = {2, 2, 4, 5, 6} which has sorted array elements and array2 = {4, 2, 6, 2, 5} that has same elements as array1 but not in sorted condition. How can I compare that both arrays have same elements. I have written the following code which works in all conditions except when array1 has two same elements and array2 has all different elements.

counter=0;
for (i=0; i<5; i++) {
for (int j=0; j<5; j++)
if (array2[i] == array1[j]) {
counter++;
array1[j]=0;

C++ :: Arrays Elements Value Limit

Apr 26, 2013

I have created a new array and have wrote a code which will decrease || increase the value of the array element. I been trying to figure out how to set the value limit. For Example:

int[] stock = new int[] { 10, 10, 10, 10 };

How to set a limit on the elements that they will never go below to the negative integers and over 10?

C/C++ :: Accessing Elements From Arrays

Feb 9, 2014

I'm confused about accessing elements from arrays. Supposed I have an array of pointers to char:

char *names = { "John", "Rose", "Steven" };

To access one of the strings, should I use names[ 0 ][ i ], where i is an index in the set ( 0, 1, 2 ), or should I use names[ i ]? I would think it would be the first option, because this array has 1 dimension that contains others arrays, right?

C/C++ :: Common Elements Of Two Arrays

Jan 23, 2015

So I'm trying to make two arrays, then the third array that will include common elements of those two arrays. I did make a code for that, but the problem is I don't know how to include that the elements do not repeat.

For example, if there are two arrays,

Elements of the first one: 2, 3

Elements of the second one: 2, 3, 2

The third array is going to be: 2 2

While I want it to be only 2.

#include <iostream>
using namespace std;
int* intersection(int* n1, int d1, int* n2, int d2, int& d3) {
d3=0;
for (int i=0; i<d1; i++) {

C/C++ :: Comparing Two Arrays For Same Elements

Feb 17, 2015

int result = 1;
for (int j=0;j<N;j++) {
bool found = false;
for (int i=0;i<N && !found;i++) {
if (a[j] == b[i]) found = true;
}
if (!found) return 0;
}

I need to create a code that compares two in arrays without sorting them. They have to be the same length and contain the same elements in any order.

every integer in a[] is also in b[]
every integer in b[] is also in a[]
all such common values appear exactly the same number of times in both a[] and b[]

EX: a = {1, 2, 3}, b = {2, 3, 4} return 0 a = {1, 2, 3}; b = {2, 3, 1} return 1 a = {1, 2, 2}; b = {2, 2, 1} return 1 a = {1, 2, 2}; b = {2, 1, 1} return 0 a = {1, 1, 2, 2, 2}; b = {2, 1, 2, 1, 2} return 1

This is all i have...

C++ :: Function That Returns Max Of A Variable Number Of Scalars

Oct 23, 2014

I need to create a function that takes as an input a variable number of scalars and returns the biggest one. Just like std::max() does for 2 elements, but I need it for an undefined number of elements, can be 2, or 5, or 10 etc.. How to approach this?

What I need it for: I'm working with a bunch of vectors, maps, etc. and I need to find out which has the most elements. So I was thinking that I should end up with something like

int biggest = max(vector1.size(), vector2.size(), map1.size(), ...);
