indirection of int in a function call

[tikelele]

Hi all,

I utilized all of the function help I got before and I am close on this one:

#include <stdio.h>
#include <math.h>
#define NumElements 5

int Square(int j)
{
    j = j * j;
    return (j);
}

int SquareArray( int num, int value)
{
    value = Square(value);
    return (value);
}
int SquareAgain (int num, int array[])
{
    int i;
    for(i = 0; i < num; i++)
    {
        array[i] = Square(array[i]);
    }
    return (array);
}

int main(int argc, char** argv)
{
    int array[NumElements] = { 1, 2, 3, 4, 5 };
    int i;
    int num;
    int value;

    printf( "array = ");
    for (i = 0; i < NumElements; i++)
    {
        printf( " &#37;d", array[i]);
    }
    printf( "  before squaring\n");

    num = i;

    printf( "array = ");
    for (i = 0; i < NumElements; i++)
    {        
        value = array[i];
        printf( " %d", SquareArray(num, value));
    }
    printf( "  after squaring\n");

    SquareAgain(num, array);

    printf( "array = ");
    for (i = 0; i < NumElements; i++)    {        
        
        printf( " %d", array[i]);
    }
    printf( "  after squaring\n");

    return ( 0 );
}

Compiles and runs with desired output but I get this warning:
Warning 1 warning C4047: 'return' : 'int' differs in levels of indirection from 'int *' 24
That's a new one on me.

line 24 = return (array);

array is int[], while you return int.
Return the same type.

[tikelele]

thanks Elysia for the reply.

so: return ( int array[] )

[tikelele]

er
return (array[])

[Elysia]

No,

int[] SquareAgain (int num, int array[])

The rest should be left as is.

[tikelele]

what a knucklehead I am!!

Thanks.

[tikelele]

actually that did not solve it at all. It made it worse.

I compiled it as is with VC++ and that is where I got the warning.

I compiled same code with gcc and no warnings at all.

Must be MS.

Thanks E

Well, I would use pointers, though, so I'm to an expert on [].

Don't return anything at all. The array is being changed in place so what's the point?
