Passing Multidimensional Arrays

ROOT
1

I’m able to pass multidimensional arrays (1-dim through 4-dim) to a function when I run it in CINT. If I try to compile it using ACLIC, it fails. How can I get it to compile correctly. Thanks.

#include <iostream>
using namespace std;
void test() {
  Int_t a[2][3]  = { {3,4,5} , {6,7,8} }; 
  funcPrint(a);
} 

void funcPrint(Int_t a[][3]) {
  for (Int_t i =0; i < 2; i++) {
    for (Int_t k = 0; k < 3; k++) {
      cout << a[i][k] << "\t";
    }
    cout << endl;
  }
}

Processing test.C++…

Hi,

Cint is more lax than ACLiC when parsing C++ code. As the error message hints:media/SPARE/star/./test.C:5: error: ‘funcPrint’ was not declared in this scope you should tell the compile what funcPrint is before using it.:[code]void funcPrint(Int_t a[][3]) ;

void test() {
Int_t a[2][3] = { {3,4,5} , {6,7,8} };
funcPrint(a);
}

void funcPrint(Int_t a[][3]) {
…[/code]

Cheers,
Philippe
