Multi-dimension array problem.

ArthurHuang · 05-20-2006, 12:11 AM

suppose I define a 3D array like " int ***dq;"

Then afte allocate memory to i, I can assign values to it:

for(1D){
for(2D){
for(3D){
dq[i][j][k]= values;

}
}
}

If I pass it as arguments of routines, I write :

fun(dq);
...

Then pass & access it in routine :

void fun(int ***dq){

dq[i][j][k];
}

IT IS CORRECT, IT IS NO PROBLEM!

However, why can't I do this to static array? I mean if I define int brr[i][j][k] and pass it to routine

fun2(brr)

Why can't I write like this:

void fun2( int ***brr){

}

It is wrong
How to pass the argument and access in routines?

Thanks a lot!

Code:

int globalarray[2][3][4];

void test(int temparray[2][3][4]) {
    int x,y,z;

    for (x=0; x<2; x++) {
        for (y=0; y<3; y++) {
            for (z=0; z<4; z++) {
                printf("temparray[%d][%d][%d]=0x%08X\n",
                    x,y,z,temparray[x][y][z]);
            }
        }
    }
}

int main() {
    memset(globalarray,0,sizeof(globalarray));
    test(globalarray);
    return 0;
}

Thanks a lot! I think too much. It's the basic of programming.
