Returning Multiple Values from a Function

[Programmer3922]

In my main I call a function to compute some things. I send in the raw data to the function.

My function then computes, averages, standard deviations etc.

I then write my return statement in the function as follows:

return(average, standardDeviation, highestNumber)

Now, when I return this to my main, how can I pick out each individual computation and store it to an appropriate variable.

I want to then pick out the data and store it as follows:

VariableOne = average;
VariableTwo = standardDeviation;

etc...

You can't return that way. Multiple returns are illegal in C. Return a struct or pass in the values by reference.

Is it possible to return an array?

[MacGyver]

Not a local one, no. You can't return an address of a local variable since local variables have the potential to be destroyed around the time as the function returns and control is given to the calling function.

And to that point, it's not legal to have an array as a return type, anyway, only a pointer. The usual method is to pass the array in as a parameter and write to it.
