Class Template in Visual C++
Hello,
I formed class template that represent two dimensional array :
Code:
template<class T>
class Array2D {
protected:
public:
T *data;
const unsigned rows, cols, size;
Array2D(unsigned r, unsigned c) : rows(r), cols(c), size(r*c) {
data = new T[size];
}
~Array2D() { delete data; }
void setValue(unsigned row, unsigned col, T value) {
data[(row*cols)+col] = value;
}
T getValue(unsigned row, unsigned col) const {
return data[(row*cols)+col];
}
};
And there is present one dimensional data array :
Code:
array<double>^ input={20,4,6,15,7,2,1,8,9};
have function it's inputs are class template and one dimensional data array.I set one dimensional array values to class template :
Code:
void function(Array2d<double> &x,array< double>^ input,int width,int,height)
{
double temp;
temp1=0;
double temp2;
int i,j;
// assign input array values to two dimensional array
for(i=0;i<width;i++)
for(j=0;j<height;j++)
{
{ temp2=input[temp1];
x.setvalue(i,j,temp2);
temp1=temp1+1;
}
}
}
After all I declared 3x3 class template:
Code:
Array2D<double>A(3,3);
I sent it to function:
Code:
function(A,input,3,3);
And I tried to print Array2D values:
Code:
double temp;
for(i=0;i<3;i++)
for(j=0;j<3;j++)
{
{temp=A.getValue(i,j)
Console:Write("{0}",temp);}}
I executed this applicaiton in CLR Application in Visual Studio 2008 amd it worked .But I want to implement this code on Windows Form Application,and it gave error like these on Form Application:
Code:
error C2065: 'Array2D' : undeclared identifier
error C2065: 'A' : undeclared identifier
How can I overcome this error or where should I locate class template?
Best Regards...
