感謝p兄指教
改成這個樣子的確就可以了:
void change(int **a, int &length)
{
delete [] *a;
length += 2;
*a = new int [length];
for(int i=0;i<length;i++) (*a)[i] = i+1;
}
int main()
{
int length = 3;
int *a = new int [length];
int **aa = &a;
for(int i=0;i<length;i++)a[i]=i+1;
for(int i=0;i<length;i++)cout<<a[i]<<" ";
for(int i=0;i<5;i++){
change(aa, length);
for(int j=0;j<length;j++)cout<<a[j]<<" ";
cout<<endl;
}
delete [] a;
return 0;
}
