hi
there is a new problem:
if i do:
int jk=(n_units*(n_units+1)/2);
cout<<"jk "<<jk<<endl;
float C_jk_arr[jk][161];
i get this error:
Error: Non-static-const variable in array dimension
FILE:c:\root\macros\ncc_ver2
.c LINE:13
(cint allows this only in interactive command and special form macro
which
is special extension. It is not allowed in source code. Please ignore
subsequent errors.)
*** Interpreter error recovered ***
if i do:
static const int jk=(n_units*(n_units+1)/2);
cout<<"jk "<<jk<<endl;
float C_jk_arr[jk][161];
then jk will be zero.
how can i do this?
thanks
i am using:
WindowsXP/NT/w2000 with VC++ 7.0, version 3.10/01 (good old tarfile) **WIN32GDK**
