printf ("%d \t", *p[i]); //printing array of pointers getch(); } Output elements at the array are : 10 20 30 Pointer to Pointer Pointer to pointer is a variable that holds the address of another pointer. Declaration datatype ** pointer_name; For example, int **p; //p ...
to pass an array of pointers to a function, you define the function parameter to match the type and size (optional) of the array. in c/c++, a function to accept an array of pointers to integers could look like void myfunction(int *arr[], int size). what happens if a pointer in ...
In the above example we defined two characters (‘ch’ and ‘c’) and a character pointer ‘ptr’. First, the pointer ‘ptr’ contained the address of ‘ch’ and in the next line it contained the address of ‘c’. In other words, we can say that Initially ‘ptr’ pointed to ‘ch...
在VBA指针Pointer里提到了3个取地址函数,VarPtr、StrPtr、ObjPtr。 其中提到了我们只需要VarPtr函数,是可以获取StrPtr、ObjPtr返回的地址的。 在VARANT里,我们讲到了Variant这个类型,它可以保存任何的类型,通过它的一个转换,我们不就可以获取到数组的地址吗? 是的,我们只要把1个数组赋值给1个Variant,然后去读取Varian...
