How to make a function to output an array?

Hi, is there any experienced trader/programmer teach me how to make a function producing multiple outputs?

I am testing if I can make a function whose output is an array of 3 values. I've looked into everywhere, and I cannot find
anything talking about how a function output multiple values, in the form of an array? or something else?

So I tried this way below. I wish the code produce an output array -- IBinfo[3] = {1,2,3} due to calling "MyFunc".
but my results is that IBinfo[3] = {11,12,13}, which is same as the initial values.

How can I make a function producing multiple outputs? This is fundamental question. If someone shows me the grammar, we don't need to look into the code below.

Thanks a lot! Thanks a lot!

//+------------------------------------------------------------------+
int start()
{

int randominput = 3;
double IBinfo[3]={11,12,13};

IBinfo[3] = MyFunc(randominput);

Print("IBinfo array reads like 3rd?: ", (IBinfo[2]+3) );
Print("IBinfo array reads like 2nd?: ", (IBinfo[1]+2) );
Print("IBinfo array reads like 1st?: ", (IBinfo[0]+1) );

return(0);
}
//+-- function of "MyFunc" -------------------------------------------+
//
double MyFunc(int randomNO)
{
double an_array[3];

for (int i=1; i<=randomNO; i++)
{
an_array[i-1]=i;
return(an_array);
}
//+-- end of MyFunc

I don't really understand what you're code is suppose to do...but i'm not a metatrader programmer either.

But to answer your question...

double Myfunc() //declare your function
{
double MyArray[3] //declare your array
MyArray[0] = x
MyArray[1] = y //define your array
MyArray[2] = z

return (MyArrray) //return your array
}

Note: syntax may not be right since i haven't done C++ in awhile.

Remember, i'm no expert, but i would try not defining your array beforehand. If you could tell us what your code is suppose to do, i might be able to help you out more. Either way, i'm sure someone more familiar with this stuff can tell you more specifics.

Thanks a lot for your help.

Your code is clear and simple, which is also good for me to show my problem.

My problem is that "How do I call for your function?"

say, if in my Start() section, I want to call "MyFunc" to produce an output for an array called "Major_array" (can hold 3 double values)
should I write:
Major_array[] = MyFunc(); or
Major_array[3] = MyFunc(); or
Major_array = MyFunc();

So far all 3 ways above to call "MyFunc" is a failure. MyFunc works alright. But I don't know the grammar to call it for a variable of an array.

Originally, what I wrote is a function may return 1. current hour; 2. current bar High, 3. current bar Low. I want to get all three values from a function. So I guess that I should make that function to fill in an array as the function output.

Then everytime I called that function, I at once have a new array containing these info (3 values).

That's why I started this.

it's simple with a pointer.
maybe there are other solutions too, but this should work fine.

Splendid idea, Siro, thank you very much, very much. This completely solve my problem!!!

However, does this mean that in MQL, a function cannot output multiple variables from within itself.

i don't know. i tryed a few things in the past to return an array with an mql function but had no luck.
