Passing in a pointer parameter to set it to another parameter

[Salad7]

Lets say we have a class named Test. I want to pass in a pointer of type int so i can set the parameter equal to my variables in my class. It's basically

Why can't i set two pointers equal to each other inside a class.

void  Test::setTest(int* ptr_param)
{

*classVar = *ptr_param;
}

try this

void  Test::setTest(int* ptr_param)
{

 classVar = ptr_param;
}

if you can please show me the whole Test class

I figured it out i was confused with pointers at the time
