pinsickle 17 Discussion Starter webdragon89 -5 pinsickle 17 Discussion Starter webdragon89 -5 Need some help with this Array. I am trying to get the sum of the even numbers and the sum of the odd numbers using a for each loop. I know the answers to what I am trying to achive are sum of even = 84 and the sum of ...

Are you talking a matrix Class or just making a matrix out of any array in main and using c style functions?

0

A matrix class.

A matrix class.

In that case you could do something like.

```
class Matrix {
public:
Matrix ();
~Matrix();
int getVal (int row, int col)const;
.........
private:
int ArrayName[what ever the row size][whatever the col size];
};
int Matrix::getVal (int row, int col)const {
return ArrayName[row][col];
}
```

In that case you could do something like.

`class Matrix { public: Matrix (); ~Matrix(); int getVal (int row, int col)const; ......... private: int ArrayName[what ever the row size][whatever the col size]; }; int Matrix::getVal (int row, int col)const { return ArrayName[row][col]; }`

I did something similar:

```
#include <iostream>
using namespace std;
class sMatrix
{
public:
sMatrix();
sMatrix(int,int);
int getR();
int getC();
bool rValid(int);
bool cValid(int);
void setEl(int,int,double);
double getEl(int i,int j);
int getVal(int,int)const;
void print();
void add();
private:
int nr, nc; //number of row and cols
int nent; //number of entries
int nmax; //the max number of entries
double *data; //store the data, the size of the storage is nmax*3
};
sMatrix::sMatrix(int rr,int cc)
{
nr=rr;
nc=cc;
nent=0;
nmax=(nr*nc)/2;
data=new double [3*nmax];
for (int i=0; i<3*nmax; i++)
data [i]=0.0;
}
int sMatrix::getR()
{
return nr;
}
int sMatrix::getC()
{
return nc;
}
bool sMatrix::rValid(int r)
{
if (r<0 || r>=nr)
return false;
return true;
}
bool sMatrix::cValid(int r)
{
if (r<0 || r>=nc)
return false;
return true;
}
void sMatrix::setEl(int r,int c, double val)
{
int i;
if (rValid(r) && cValid(c))
{
i=3*nent;
data[i]=r;
data[i+1]=c;
data[i+2]=val;
nent++;
}
}
void sMatrix::print()
{
int i;
for (i=0;i<3*nent;i+=3)
{
cout<<"<"<<data[i]<<",";
cout<<""<<data[i+1]<<",";
cout<<""<<data[i+2]<<">"<<endl;
}
}
int sMatrix::getVal(int row,int col)const
{
return nmax[row][col];
}
void sMatrix::add()
{
int i,j;
for (i=0;i<=nr;i++)
{
for (j=0;j<=nc;j++)
{
m(i,j)+=n(i,j); //m and n undeclared identifier
}
}
}
void main ()
{
sMatrix M(3,3), N(3,3);
M.setEl(0,0,3);
M.setEl(1,1,4);
M.setEl(2,0,2.4);
M.print();
N.setEl(0,0,3);
N.setEl(1,1,4);
N.setEl(2,0,2.4);
N.print();
M.add(N); // function does not take 1 arguments
}
//For the rest of the project it needs:
//1) a getVal function that retrieves the value of the element row i and column j.
//(The function mst check both i and j values are in range)
//2)Provide a putVal function that puts a value v in rown i and column j.
//This operation must make sure that i and j values do not exists in the storage.
//3) a funtion to print the matrix in full form or in triple form.
//4) should do addition, subtraction, and multiplication
```

As you can see theres a few mistakes, part of the code was given in class and I've been trying to make it do what has to be done.
