![int xRes-512, yRes-256;
float *xtable; // pointer to pointer[s]
xtable = new float [yRes]; // a ("column") array to hold 'float
type pointers
// each element of the above array points to a 'row' of xRes elements

Create an 'array2D' class that encapsulates the above. Your class should contain the following 'protected'
members ("protected members are accessible in the class that defines them, AND in classes that inherit from it"]:
• xtable
• xRes
* VRes
It should also contain the following public interface:
• constructor: array2D(xResolution,yResolution)
• getSize(int &xResolution, int &yResolution) ['&' because we want those vars to be SET inside the function, like a 'return' in a way: confusingly, int
xResolution&, int yResolution& means the same thing!)
• setvalue(x.y,val) [at (x.v), store val (in xtable, y would be the rowlD, x, the columniD)]
• setValue(x,y,val) [at (x,v), store val (in xtable, y would be the rowID, x, the columnID)]
• val=getValue(x,v) [at (x,y), retrieve val]
Remember to create a destructor function as well :)
Exercise your array2D class as follows, inside main():
array2D *a = new array2D(320, 24e);
int xRes, yRes;
a->getsize(XRes, yRes);
// NOTE the j,i ordering below (twice), since we specify coords as (x,y) [not (y,x)]
for(int i-0;i < yRes;i++){
for (int j=0;j < xRes;j++){
a->setvalue(j,i,100); // constant value of 100 at all locations
for (int i=0;i < yRes;i++){
for(int j=e;j < xRes;j++){
cout « a->getvalue(j,i) <« " ";
cout <« endl;
}
