The correct syntax to declare a pointer in C++ is `int *ptr;`. Here's the step by step explanation:

1. `int`: This is the data type of the variable that the pointer is going to point to. In this case, the pointer will point to an integer.

2. `*`: The asterisk is used to denote that this is a pointer variable, i.e., it can hold the address of another variable.

3. `ptr`: This is the name of the pointer variable. You can choose any valid variable name.

So, `int *ptr;` declares a pointer named ptr that can hold the address of an integer variable.
