What's Wrong with this C Excert

[Albert Wu]

The following is part of an example I saw on p.301 of Byron S.
Gottfried's Schaum's Outline Series "Programming with C", copyrighted
1990.  It doesn't compile.  Can anyone tell me what's wrong ?  I am
a total beginner in C.  Pls don't laugh.


#include <stdio.h>

#define MAXCOLS 30

main()
{
        int (*a)[MAXCOLS],(*b)[MAXCOLS],(*c)[MAXCOLS];

	.........

        *a = (int*) malloc (rows * ncols * sizeof(nt));
        *b = (int*) malloc ( nrows * ncols * sizeof(int));
        *c =(int*) malloc ( nrows * ncols * sizeof(int));
}
