问题描述

读一段c++源代码，里面的array类里面的输出函数，看不懂什么意思。

template //看不懂
void array::print(void)
{
if(dim_3==1)
{
int ijk;
bool threeD = (dim_2==1?false:true);
for (k = 0; k< dim_2; k++)
{
if (threeD)
cout<<endl<<""ans(::<<k+1<<"") = ""<<endl;
for(i=0; i<dim_0; i++)
{
for(j=0; j<dim_1; j++)
{

              if((*this)(ijk)*(*this)(ijk)<1e-12)                {                  cout << "" 0 "";                }              else                {                  cout << "" "" << (*this)(ijk) << "" "";                }            }          cout << endl;        }      if (threeD)        cout<<endl;    }}

else
{
cout << ""ERROR: Can only print an array of dimension three or less ...."" << endl;
}
}
