casting

**SnS CEO** · 08-08-2005

My specific question is: how do I fix this problem:

Code:

if(whitepiece[index].jumpup(xposition2, yposition2, matrix) == 0 && whitepiece[index].moveup(xposition2, yposition2, matrix == 0))

C:\PROGRAM FILES\MICROSOFT VISUAL STUDIO\MYPROJECTS\SnSCheckers\main.cpp(173) : error C2664: 'moveup' : cannot convert parameter 3 from 'bool' to 'int [][8]'
        Conversion from integral type to pointer type requires reinterpret_cast, C-style cast or function-style cast

the .moveup and .jumpup functions return a bool and the matrix is [int][int].

And in general, when does one need to typecast?

Generally that sort of an error, pointer to integer, or integer to pointer, means you're passing the wrong thing to a function. Specifically, it means where you're supposed to be using an integer, you're using a pointer. In this case, it means you're doing something like this:

Code:

void foo( int bar[][SOMESIZE] );

int x;

foo( x );

This is clearly wrong, because this function wants a two dimensional array, and you're simply passing it one integer. A cast would most definately be wrong here. The correct thing to do would be to pass it what it expects you to pass it, and not something incorrect.

caught my mistake, I just had a misplaced )

so I <i>was</i> passing it the right data type...
