类成员数组赋值问题~跪求各位大哥指点

#include<iostream.h>
#include<math.h>
class array       
{
 public:
 double *A[58];
 array *ptr;
 void initialize(void);
 void output(array *ptr);
};
array EOSAI;
main()
{
 EOSAI.initialize();
 EOSAI.output(EOSAI.ptr);
}
void array::initialize(void)
{
 int a,b;
 double B[59]={0,0.153832600e0,1.341953000e0,-2.998583000e0,-0.048312280e0,0.375796500e0,-1.589575000e0,-0.053588470e0

  b=58;
 EOSAI.ptr=&EOSAI;
 for(a=0;a<=b;a++)
 {
  EOSAI.ptr->A[a]=B[a];     //此行错误！！！！！！！！！！！！！！
 }
}
void array::output(array *ptr)
{
 int a,b;
 b=58;
 for(a=0;a<=b;a++)
 {
  cout<<A[a]<<"\n";
 }
}
错误出在此行：  EOSAI.ptr->A[a]=B[a];     显示是illegal use of floating point
我还写过小程序试过，整数数组就没问题，一旦改成float或者double即使编译时不出错，运行时也会出错：General Protection Fault in module
PS:类成员数组赋值问题好烦啊，有没有大虾给个较好的方法可以批量给类成员double数组赋值，我正把一个fortran程序改写成C++，超多的全局变量需要赋值。大家有没有什么好办法对付Fortran中大量的common变量呀。。。。。
