returning array

It is possible to return a array from a function to main?

First, this should be in either in the C or C++ forum, not Windows. And yes there is a way to do it, here's how:

Code:

//Program that returns an array of intigers

#include <stdio.h>
#include <stdlib.h>

int * GetArray( int intA, int intB, int intC );

int main(void)
{

    int * arrayPtr;

    arrayPtr = GetArray( 1, 2, 3 );

    printf( "%d %d %d\n", arrayPtr[0], arrayPtr[1], arrayPtr[2] );

    free( (void *) arrayPtr );  //Free dynamically allocated memory once you finish with it to avoid memory leaks 

    system( "PAUSE" );

    return 0;

}

int * GetArray( int intA, int intB, int intC )
{

    int * arrayPtr = (int *) malloc( sizeof( int ) * 3 );  //If you allocate the array withing the funtion malloc must be used or the the array be deallocated when the function exits

    arrayPtr[0] = intA;
    arrayPtr[1] = intB;
    arrayPtr[2] = intC;

    return arrayPtr;

}

This kind of stuff involves some fancy tricks with pointers an memory allocation so if there's anything you don't understand let me know

Sorry, posted at the wrong place.

So this is using a pointer to point to a array in the function then pass the pointer back to the main?

Just think of array[] as *array. Like was sown above, to return an array just set the return type as TYPE * ... The same goes for passing values.

Alternatively return an std::vector.
