write the heading function that take two arrays, and return a bool result in C++ program

I had write the three arrays type called DataSet with three arrays: input, output, and working. Each array hole 5 float values.

const MY_INPUT =4;
const MY_OUTPUT = 4;
const MY_WORKING = 4;
float DataSet[MY_INPUT][MY_OUTPUT][MY_WORKING];
float input;
float output;
float working;
And now I need to write a heading function called Equals that take two arrays for the DataSet type and returns a bool result. The array parameters should be const, as they are input-only parameters to the function , but I got stuck on it, could you help me for the solution to complete this part. Thank you very much for your help.

if you want a type holding three arrays then do.

const int MY_INPUT = 5;
const int MY_OUTPUT = 5;
const int MY_WORKING = 5;
typedef struct THREE_ARRAYS_TAG
{
     float input[MY_INPUT];
     float output [MY_OUTPUT];
     float working[MY_WORKING];
}  THREE_ARRAYS;

Open in new window

you could pass any of those arrays by defining a variable of type THREE_ARRAYS
and then use the member variable like

THREE_ARRAYS ta;
/* fill the arrays */
 ...
if (func(ta.input,  MY_INPUT ))
     ...

Open in new window

the function could be defined as 'bool func(const float* input , int elements)';

You can use typdef to define the 3d type.
Example:

const int MY_INPUT =4;
const int MY_OUTPUT = 4;
const int MY_WORKING = 4;

typedef float MY_3D_DATASETTYPE[MY_INPUT][MY_OUTPUT][MY_WORKING];

bool MyFunction(MY_3D_DATASETTYPE &DataSet)
{
	return false;
}

// ... Some code usage:
	float DataSet[MY_INPUT][MY_OUTPUT][MY_WORKING] = {0};
	MyFunction(DataSet);

I would recommend using vector< vector< vector<float> > > type over C style 3D array type.
