'int' is short for integer and is a data type used in C++, while '*' denotes a pointer. Therefore, the statement 'Int *ptr = nullptr;' declares a pointer variable 'ptr' which can store the memory address of an integer variable (i.e., a variable of type 'int'). The initial value of this pointer variable is 'nullptr', which is a pointer literal representing a null pointer, meaning that 'ptr' currently does not point to any valid memory address.
