Aminu Abdulkadir by putting * (asterisk) between type and variable identifier (name): int *my_int; or: int * my_int; or: int* my_int; would declare a pointer to an int ^^

Pointers can be initialised to NULL, which is good practice, if you're not immediately assigning the address of a memory block to it.

It depends on whether the pointer points to an integer (int*), character(char*), float(float*), double(double*) etc.

Your thread will look better if you move the title text 'C++' into the tags, and the Description text 'How to declare pointer in C++' in the question title 👍

however, you need to assign a valid memory address to it (another existing variable address or a dynamic allocated memory space address)
