Getting multdimensional array as input and returning a const unsigned char as output

VPadmanabhan (1)
Hi,

I am trying to create a class to get the input as multidimensional array from another class as color[] width[] height[] and create an output as unsigned char[....] Till now I have done this but the console gets stuck when I give the input values... It would be great to know if there is a way to get input as three dimensional array and create an output as single dimension....

dont manipulate vector by index [] the way you do - it is unsafe and error prone ( like c0000005).
create structure:
1
2
3
4
5
6
 
struct some_name_t
{
int color;
int width;
int height;
};


and then put it in they vector, like:
std::vector <some_name_t>
